    Extracellular vesicles (EVs), including exosomes, are recognized as promising functional targets involved in disease mechanisms. However, the intravital heterogeneity of EVs remains unclear, and the general limitation for analyzing EVs is the need for a certain volume of biofluids. Here, we present cellulose nanofiber (CNF) sheets to resolve these issues. We show that CNF sheets capture and preserve EVs from ~10 μL of biofluid and enable the analysis of bioactive molecules inside EVs. By attaching CNF sheets to moistened organs, we collect EVs in trace amounts of ascites, which is sufficient to perform small RNA sequence analyses. In an ovarian cancer mouse model, we demonstrate that CNF sheets enable the detection of cancer-associated miRNAs from the very early phase when mice did not have apparent ascites, and that EVs from different locations have unique miRNA profiles. By performing CNF sheet analyses in patients, we identify further location-based differences in EV miRNA profiles, with profiles reflecting disease conditions. We conduct spatial exosome analyses using CNF sheets to reveal that ascites EVs from cancer patients exhibit location-dependent heterogeneity. This technique could provide insights into EV biology and suggests a clinical strategy contributing to cancer diagnosis, staging evaluation, and therapy planning.

    Arrays of small reaction containers, ranging from 624 femtoliters (10–15 L) to 270 attoliters (10–18 L), for capturing a single enzyme molecule and measuring the activity were developed along with a new reversible sealing system based on a pneumatic valve actuator made of polydimethylsiloxane (PDMS). The valve was actuated by PBS solution, effectively preventing evaporation of the solution from the micro- and nanochambers and allowing the assay to be performed over a long period of time. The hydrolysis rates of β-D-galactosidase (β-gal), kcat, were decreased according to the decrease of the chamber size, and the overall tendency seems to be symmetrically related to the specific surface area of the chambers even under the prevented condition of non-specific adsorption. The spatial localization of the protons in the chambers, which might could affect the dissociation state of the proteins, was also investigated to explain the decrease in the hydrolysis rate. The developed chamber system developed here may be useful for artificially reproducing the confined intracellular environment and molecular crowding conditions.

    Background: Near-infrared photoimmunotherapy (NIR-PIT) is a promising cancer therapy combining NIR-light irradiation with an antibody and IR700DX, a light-sensitive substance, to destroy tumours. However, homogeneous irradiation is difficult because the light varies depending on the distance and tissue environment. Therefore, markers that indicate sufficient irradiation are necessary. Nanoparticles sized 10∼200 nm show enhanced permeation and retention within tumours, which is further enhanced via NIR-PIT (super enhanced permeability and retention, SUPR). We aimed to monitor the effectiveness of NIR-PIT by measuring SUPR. Methods: A xenograft mouse tumour model was established by inoculating human cancer cells in both buttocks of Balb/C-nu/nu mice, and NIR-PIT was performed on only one side. To evaluate SUPR, fluorescent signal examination was performed using QD800-fluorescent nanoparticles and NIR-fluorescent poly (D,L-lactide-co-glycolic acid) (NIR-PLGA) microparticles. Harmonic signals were evaluated using micro-bubbles of the contrast agent Sonazoid and contrast-enhanced ultrasound (CEUS) imaging. The correlation between SUPR immediately after treatment and NIR-PIT effectiveness on the day after treatment was evaluated. Findings: QD800 fluorescent signals persisted only in the treated tumours, and the intensity of remaining signals showed high positive correlation with the therapeutic effect. NIR-PLGA fluorescent signals and Sonazoid-derived harmonic signals remained for a longer time in the treated tumours than in the controls, and the kE value of the two-compartment model correlated with NIR-PIT effectiveness. Interpretation: SUPR measurement using Sonazoid and CEUS imaging could be easily adapted for clinical use as a therapeutic image-based biomarker for monitoring and confirming of NIR-PIT efficacy.

    A low-temperature Al2O3 deposition process provides a simplified method to form a conductive two-dimensional electron gas (2DEG) at the metal oxide/Al2O3 heterointerface. However, the impact of key factors of the interface defects and cation interdiffusion on the interface is still not well understood. Furthermore, there is still a blank space in terms of applications that go beyond the understanding of the interface’s electrical conductivity. In this work, we carried out a systematic experimental study by oxygen plasma pretreatment and thermal annealing post-treatment to study the impact of interface defects and cation interdiffusion at the In2O3/Al2O3 interface on the electrical conductance, respectively. Combining the trends in electrical conductance with the structural characteristics, we found that building a sharp interface with a high concentration of interface defects provides a reliable approach to producing such a conductive interface. After applying this conductive interface as electrodes for fabricating a field-effect transistor (FET) device, we found that this interface electrode exhibited ultrastability in phosphate-buffered saline (PBS), a commonly used biological saline solution. This study provides new insights into the formation of conductive 2DEGs at metal oxide/Al2O3 interfaces and lays the foundation for further applications as electrodes in bioelectronic devices.

    Cancer cell-derived extracellular vesicles (EVs) have unique protein profiles, making them promising targets as disease biomarkers. High-grade serous ovarian carcinoma (HGSOC) is the deadly subtype of epithelial ovarian cancer, and we aimed to identify HGSOC-specific membrane proteins. Small EVs (sEVs) and medium/large EVs (m/lEVs) from cell lines or patient serum and ascites were analyzed by LC-MS/MS, revealing that both EV subtypes had unique proteomic characteristics. Multivalidation steps identified FRα, Claudin-3, and TACSTD2 as HGSOC-specific sEV proteins, but m/lEV-associated candidates were not identified. In addition, for using a simple-to-use microfluidic device for EV isolation, polyketone-coated nanowires (pNWs) were developed, which efficiently purify sEVs from biofluids. Multiplexed array assays of sEVs isolated by pNW showed specific detectability in cancer patients and predicted clinical status. In summary, the HGSOC-specific marker detection by pNW are a promising platform as clinical biomarkers, and these insights provide detailed proteomic aspects of diverse EVs in HGSOC patients.

    Quantum dots (QDs) have attracted attention for their application and commercialization in all industrial fields, including communications, displays, and solar cells, due to their excellent optical properties based on the quantum size effect. In recent years, the development of QDs that do not contain cadmium which is toxic to cells and living organisms, has progressed, and they have attracted considerable attention in the bio-imaging field for targeting molecules and cells. Furthermore, recently, the need for diagnostics and treatment at the single molecule and single cell level in the medical field has been increasing, and the application of QDs in the medical field is also accelerating. Therefore, this paper outlines the frontiers of diagnostic and therapeutic applications (theranostics) of QDs, especially in advanced medical fields such as regenerative medicine, oncology, and infectious diseases.

    <p>The use of small drones has led to more remote and manpower-saving industrial inspections. Furthermore, they are expected to be applied to environmental surveys of closed indoor spaces. Adding functionality to small drones is subject to payload limitations. We have developed a device to capture aerosols on the propeller surface of a small drone flying over an inspection site. It was demonstrated that the airflow generated by the drone during flight was directed toward the center of rotation of the propeller and collected airborne particulate matter on the air filter on the propeller surface. The collected material was available for individual particle analysis by electron microscopy.</p>

    Various liquid biopsy methods have been developed for the non-invasive and early detection of diseases. In particular, the detection of circulating tumor cells (CTCs) and cancer-associated fibroblasts (CAFs) in blood has been receiving a great deal of attention. We have been developing systems and materials to facilitate such liquid biopsies. In this study, we further developed glass filters (with various patterns of holes, pitches, and non-adhesive coating) that can capture CTCs, but not white blood cells. We optimized the glass filters to capture CTCs, and demonstrated that they could be used to detect CTCs from lung cancer patients. We also used the optimized glass filters for detecting CAFs. Additionally, we further developed a system for visualizing the captured cells on the glass filters. Finally, we demonstrated that we could directly culture the captured cells on the glass filters. Based on these results, our high-performance glass filters appear to be useful for capturing and culturing CTCs and CAFs for further examinations.

    Stem cell therapy plays an important role in regenerative therapy; however, there is little information on the in vivo dynamics of transplanted stem cells and the influence of the inflammation of affected tissues or organs on these dynamics. In this study, we revealed real-time dynamics of transplanted adipose tissue-derived stem cells (ASCs) and the influence of the inflammatory states on these dynamics in acute liver failure mice. Quantum dots (QDs) labeling did not affect the cytokine profile of ASCs, and intravenously transplanted ASCs labeled with QDs could be detected in real time with high efficiency without laparotomy. Until 30 min after ASC transplantation, no marked differences in the behavior or accumulation of transplanted ASCs in the liver were observed among the three groups with different degrees of liver damage (normal, weak, and strong). However, significant differences in the engraftment rate of transplanted ASCs in the liver were observed among the three groups from 4 h after transplantation. The engraftment rate was inversely correlated with the extent of the liver damage. These data suggested that QDs are useful for in vivo real-time imaging of transplanted cells, and the inflammatory state of tissues or organs may affect the engraftment rate of transplanted cells.

    Energy dissipation in solid-state nanopores is an important issue for their use as a sensor for detecting and analyzing individual objects in electrolyte solution by ionic current measurements. Here, we report on evaluations of heating via diffusive ion transport in the nanoscale conduits using thermocouple-embedded SiNx pores. We found a linear rise in the nanopore temperature with the input electrical power suggestive of steady-state ionic heat dissipation in the confined nanospace. Meanwhile, the heating efficiency was elucidated to become higher in a smaller pore due to a rapid decrease in the through-water thermal conduction for cooling the fluidic channel. The scaling law suggested nonnegligible influence of the heating to raise the temperature of single-nanometer two-dimensional nanopores by a few kelvins under the standard cross-membrane voltage and ionic strength conditions. The present findings may be useful in advancing our understanding of ion and mass transport phenomena in nanopores.

    Humidity and moisture effects, frequently called water poisoning, in surroundings are inevitable for various molecular sensing devices, strongly affecting their sensing characteristics. Here, we demonstrate a water-selective nanostructured dehumidifier composed of ZnO/TiO2/CaCl2 core-shell heterostructured nanowires for molecular sensing spaces. The fabricated nanostructured dehumidifier is highly water-selective without detrimental adsorptions of various volatile organic compound molecules and can be repeatedly operated. The thermally controllable and reversible dehydration process of CaCl2·nH2O thin nanolayers on hydrophilic ZnO/TiO2 nanowire surfaces plays a vital role in such water-selective and repeatable dehumidifying operations. Furthermore, the limitation of detection for sensing acetone and nonanal molecules in the presence of moisture (relative humidity ∼90%) was improved more than 20 times using nanocomposite sensors by operating the developed nanostructured dehumidifier. Thus, the proposed water-selective nanostructured dehumidifier offers a rational strategy and platform to overcome water poisoning issues for various molecular and gas sensors.

    Cancer-derived small extracellular vesicles (sEVs) are multifunctional particles with a lipid bilayer structure that are involved in cancer progression, such as malignant proliferation, distant metastasis, and cancer immunity evasion. The separation protocol used to isolate sEVs is an important process and thus, several have been developed, including ultracentrifugation (UC), size exclusion chromatography (SEC), and affinity purification using antibodies against sEV surface antigens. However, the effects of different separation methods on sEV components have not been adequately examined. Here, we developed a semi-automated system for collecting sEVs by combining SEC and preparative high-performance liquid chromatography and applied it to metabolome analysis. The developed SEC system could recover sEVs more efficiently and non-destructively than UC, suggesting that it is an appropriate recovery method for metabolic analysis and reflects biological conditions. Furthermore, using the developed SEC system, we performed metabolome analysis of sEVs from isocitrate dehydrogenase 1 (IDH)-mutated human colon HCT116 cells, which produce the oncogenic metabolite, 2-hydroxyglutaric acid (2-HG). IDH1-mutated HCT116 cells released significantly more sEVs than wild-type (WT) cells. The metabolomic profiles of IDH1 mutant and WT cells showed distinct differences between the cells and their sEVs. Notably, in IDH mutant cells, large amounts of 2-HG were detected not only in cells, but also in sEVs. These results indicate that the SEC system we developed has wide potential applications in sEVs research.

    Multinary semiconductor quantum dots (QDs) composed of group I-III-VI elements have received much attention for wide-ranging applications due to their low level of toxicity and tunable optical properties. The chemical composition and particle size are important parameters for controlling the physicochemical properties of these QDs. In this study, we prepared quinary QDs of an Ag-(In,Ga)-(S,Se) semiconductor (AIGSSe) by thermolysis of precursors in an organic solution with two-step heat treatment and evaluated their physicochemical properties as a function of Se fraction. The energy gap (Eg) of QDs decreased from 1.9 to 1.5 eV with an increase in the Se/(S + Se) ratio from 0 to 1, accompanied by a shift of the valence band maximum to a higher energy level. The obtained AIGSSe QDs exhibited a sharp band-edge PL peak, the wavelength of which was red-shifted from 580 to 790 nm with a decrease in theirEg. The PL intensity was remarkably enlarged by the surface coating with a GaSxshell, the highest PL quantum yield being 50% for the PL peak at 580 nm. AIGSSe QDs with an Se/(S + Se) ratio of 0.50 exhibited a near-IR PL peak at 790 nm, which is suitable forin vivobioimaging in the wavelength range of the first biological window. By incorporating GaSx-coated AIGSSe QDs (Se/(S + Se) = 0.50) into liposomes, the QDs were transferred into aqueous solutions without significant deterioration of both the PL peak outline and quantum yield, though a broad PL peak originating from defect sites appeared with a relatively large PL intensity when GaSx-coated Ag-(In,Ga)-S QDs that did not contain Se were used.In vivoimaging of a mouse was successfully performed by detecting the band-edge emission at 790 nm of AIGSSe QDs injected subcutaneously in the back of the mouse.

    This study developed low‐cost and highly sensitive immunoassay devices possessing the ability to rapidly analyze urine samples. Further, they can quantitatively detect three biomarkers indicating renal injury: monocyte chemotactic protein 1 (MCP‐1), angiotensinogen (AGT), and liver-type fatty acid binding protein (L‐FABP). The devices were used to successfully estimate the concentrations of the three biomarkers in urine samples within 2 min; the results were consistent with those obtained via conventional enzyme‐linked immunosorbent assay (ELISA), which requires several hours. In addition, the estimated detection limits for the three biomarkers were comparable to those of commercially available ELISA kits. Thus, the proposed and fabricated devices facilitate high‐precision and frequent monitoring of renal function.

    Extracellular vesicles (EVs) have shown promising features as biomarkers for early cancer diagnoses. The outer layer of cancer cell-derived EVs consists of organotropic metastasis-induced membrane proteins and specifically enriched proteoglycans, and these molecular compositions determine EV surface charge. Although many efforts have been devoted to investigating the correlation between EV subsets obtained through density-, size-, and immunoaffinity-based captures and expressed membrane proteins, understanding the correlation between EV subsets obtained through surface charge-based capture and expressed membrane proteins is lacking. Here, we propose a methodology to profile membrane proteins of EV subsets obtained through surface charge-based capture. Nanowire-induced charge-based capture of EVs and in-situ profiling of EV membrane proteins are the two key methodology points. The oxide nanowires allowed EVs to be obtained through surface charge-based capture due to the diverse isoelectric points of the oxides and the large surface-to-volume ratios of the nanowire structures. And, with the ZnO nanowire device, whose use does not require any purification and concentration processes, we demonstrated the correlation between negatively-charged EV subsets and expressed membrane proteins derived from each cell. Furthermore, we determined that a colon cancer related membrane protein was overexpressed on negatively charged surface EVs derived from colon cancer cells.

    Amplification-free genome analysis can revolutionize biology and medicine by uncovering genetic variations among individuals. Here, the authors report on a 3D-integrated nanopore for electrolysis to in situ detection of single-molecule DNA in a cell by ionic current measurements. It consists of a SiO2 multipore sheet and a SiNx nanopore membrane stacked vertically on a Si wafer. Single cell lysis is demonstrated by 106 V m−1-level electrostatic field focused at the multinanopore. The intracellular molecules are then directly detected as they move through a sensing zone, wherein the authors find telegraphic current signatures reflecting folding degrees of freedom of the millimeter-long polynucleotides threaded through the SiNx nanopore. The present device concept may enable on-chip single-molecule sequencing to multi-omics analyses at a single-cell level.

    Since DNA analysis is the fundamental process for most applications in biomedical fields, capturing DNAs with high efficiency is important. Here, we used several oxide nanowire microfluidic devices to capture CpG-rich single-stranded DNAs (ssDNAs) in different pH solutions. All the oxide nanowires exhibited the highest capture efficiency around pH 7 with good capture efficiency shown by each metal oxide; ZnO/ZnO core/shell NWs (71.6%), ZnO/Al2O3 core/shell NWs (86.3%) and ZnO/SiO2 core/shell NWs (86.7%). ZnO/Al2O3 core/shell NWs showed the best performance for capturing ssDNAs under varying pH, which suggests its suitability for application in diverse biological fluids. The capturing efficiencies were attributed to the interactions from phosphate backbones and nucleobases of ssDNAs to each nanowire surface. This finding provides a useful platform for highly efficient capture of the target ssDNAs, and these results can be extended for future studies of cancer-related genes in complex biological fluids.

    We investigated the microfabrication of PCR reaction vessel, capillary array electrophoresis (CAE), and laser-induced fluorescence detection cell using synchrotron radiation in polymethylmethacrylate (PMMA) substrates towards the development of novel technology for ultra-fast DNA analysis. Laser-induced fluorescence detection system for the chip has been developed and successfully applied to the imaging of a band for DNA fragment labeled by fluorescent dye during migrating in the array of microchannels to optimize the separation conditions for DNA analysis. Based on the imaging data, we can estimate that 10-s separation of some DNA fragments will be achievable using 10-mm separation channel on a chip.

    RNA analytical platforms gained extensive attention recently for RNA-based molecular analysis. However, the major challenge for analyzing RNAs is their low concentration in blood plasma samples, hindering the use of RNAs for diagnostics. Platforms that can enrich RNAs are essential to enhance molecular detection. Here, we developed the annealed ZnO/Al2O3 core-shell nanowire device as a platform to capture RNAs. We showed that the annealed ZnO/Al2O3 core-shell nanowire could capture RNAs with high efficiency compared to that of other circulating nucleic acids, including genomic DNA (gDNA) and cell-free DNA (cfDNA). Moreover, the nanowire was considered to be biocompatible with blood plasma samples due to the crystalline structure of the Al2O3 shell which serves as a protective layer to prevent nanowire degradation. Our developed device has the potential to be a platform for RNA-based extraction and detection.

    Methods that can rapidly and accurately extract or isolate nucleic acids would facilitate the capability for scientists to access key information regarding nucleic acid molecular signatures. Knowing these molecular signatures could contribute to development of strategies for detecting, treating, and diagnosing diseases based on nucleic acids. However, major impediments to accessing nucleic acids are their natural characteristics, including concentration and size. Here we review the development of nanomaterial-based devices to isolate circulating nucleic acids from biological samples, including blood, urine, cell, and virus; these devices enable enhancement of isolation and extraction efficiency compared to conventional methods.

    Field-effect transistors (FETs) are attractive biosensor platforms for rapid and accurate detection of various analytes through surface immobilization of specific bio-receptors. Since it is difficult to maintain the electrical stability of semiconductors of sensing channel under physiological conditions for long periods, passivation by a stable metal oxide dielectric layer, such as Al2O3 or HfO2, is currently used as a common method to prevent damage. However, protecting the sensing channel by passivation has the disadvantage that the distance between the target and the conductive channel increases, and the sensing signal will be degraded by Debye shielding. Even though many efforts use semiconductor materials directly as channels for biosensors, the electrical stability of semiconductors in the physiological environments has rarely been studied. In this work, an In2O3 nanolines FET device with high robustness in artificial physiological solution of phosphate buffered saline (PBS) was fabricated and used as a platform for biosensors without employing passivation on the sensing channel. The FET device demonstrated reproducibility with an average threshold voltage (VTH) of 5.235 V and a standard deviation (SD) of 0.382 V. We tested the robustness of the In2O3 nanolines FET device in PBS solution and found that the device had a long-term electrical stability in PBS with more than 9 days’ exposure. Finally, we demonstrated its applicability as a biosensor platform by testing the biosensing performance towards miR-21 targets after immobilizing the phosphonic acid terminated DNA probes. Since the surface immobilization of multiple bioreceptors is feasible, we demonstrate that the robust In2O3 FET device can be an excellent biosensor platform for biosensors.

    A rapid and simple cancer detection method independent of cancer type is an important technology for cancer diagnosis. Although the expression profiles of biological molecules contained in cancer cell-derived extracellular vesicles (EVs) are considered candidates for discrimination indexes to identify any cancerous cells in the body, it takes a certain amount of time to examine these expression profiles. Here, we report the shape distributions of EVs suspended in a solution and the potential of these distributions as a discrimination index to discriminate cancer cells. Distribution analysis is achieved by low-aspect-ratio nanopore devices that enable us to rapidly analyze EV shapes individually in solution, and the present results reveal a dependence of EV shape distribution on the type of cells (cultured liver, breast, and colorectal cancer cells and cultured normal breast cells) secreting EVs. The findings in this study provide realizability and experimental basis for a simple method to discriminate several types of cancerous cells based on rapid analyses of EV shape distributions.

    There are no accurate mass screening methods for early detection of central nervous system (CNS) tumors. Recently, liquid biopsy has received a lot of attention for less-invasive cancer screening. Unlike other cancers, CNS tumors require efforts to find biomarkers due to the blood-brain barrier, which restricts molecular exchange between the parenchyma and blood. Additionally, because a satisfactory way to collect urinary biomarkers is lacking, urine-based liquid biopsy has not been fully investigated despite the fact that it has some advantages compared to blood or cerebrospinal fluid-based biopsy. Here, we have developed a mass-producible and sterilizable nanowire-based device that can extract urinary microRNAs efficiently. Urinary microRNAs from patients with CNS tumors (n = 119) and noncancer individuals (n = 100) were analyzed using a microarray to yield comprehensive microRNA expression profiles. To clarify the origin of urinary microRNAs of patients with CNS tumors, glioblastoma organoids were generated. Glioblastoma organoid-derived differentially expressed microRNAs (DEMs) included 73.4% of the DEMs in urine of patients with parental tumors but included only 3.9% of those in urine of noncancer individuals, which suggested that many CNS tumor-derived microRNAs could be identified in urine directly. We constructed the diagnostic model based on the expression of the selected microRNAs and found that it was able to differentiate patients and noncancer individuals at a sensitivity and specificity of 100 and 97%, respectively, in an independent dataset. Our findings demonstrate that urinary microRNAs extracted with the nanowire device offer a well-fitted strategy for mass screening of CNS tumors.

    Seeded crystal growths of nanostructures within confined spaces offer an interesting approach to design chemical reaction spaces with tailored inner surface properties. However, such crystal growth within confined spaces tends to be inherently difficult as the length increases as a result of confinement effects. Here, we demonstrate a space-confined seeded growth of ZnO nanowires within meter-long microtubes of 100 μm inner diameter with the aspect ratio of up to 10 »000, which had been unattainable to previous methods of seeded crystal growths. ZnO nanowires could be grown via seeded hydrothermal crystal growth for relatively short microtubes below the length of 40 mm, while any ZnO nanostructures were not observable at all for longer microtubes above 60 mm with the aspect ratio of 600. Microstructural and mass spectrometric analysis revealed that a conventional seed layer formation using zinc acetate is unfeasible within the confined space of long microtubes as a result of the formation of detrimental residual Zn complex compounds. To overcome this space-confined issue, a flow-assisted seed layer formation is proposed. This flow-assisted method enables growth of spatially uniform ZnO nanowires via removing residual compounds even for 1 m long microtubes with the aspect ratio of up to 10 »000. Finally, the applicably of ZnO-nanowire-decorated long microtubes for liquid-phase separations was demonstrated.

    Detection of cell-free DNA (cfDNA) has an impact on DNA analysis in liquid biopsies. However, current strategies to detect cfDNA have limitations that should be overcome, such as having low sensitivity and requiring much time and a specialized instrument. Thus, non-invasive and rapid detection tools are needed for disease prevention and early-stage treatment. Here we developed a device having a microheater integrated with zinc oxide nanowires (microheater-ZnO-NWs) to detect target single-stranded DNAs (ssDNAs) based on DNA probe hybridization. We confirmed experimentally that our device realized in-situ annealed DNA probes by which we subsequently detected target ssDNAs. We envision that this device can be utilized for fundamental studies related to nanobiodevice-based DNA detection.

    Recent studies have shown that extracellular vesicles (EVs) can be utilized as appropriate and highly specific biomarkers in liquid biopsy for the diagnosis and prognosis of serious illness. However, there are few methods that can collect and isolate miRNA in EVs simply, quickly and efficiently using general equipment such as a normal centrifuge. In this paper, we developed an advanced glass membrane column (AGC) device incorporating a size-controlled macro-porous glass (MPG) membrane with a co-continuous structure to overcome the limitations of conventional EV collection and miRNA extraction from the EVs. The size of macro-pores in the MPG membrane could be accurately controlled by changing the heating temperature and time on the basis of spinodal decomposition of B2O3, Na2O, and SiO2 in phase separation. The AGC device with an MPG membrane could collect the EVs simply and quickly (< 10 min) from cell culture supernatant, serum and urine. This AGC device could extract miRNA from the EVs captured in the MPG membrane with high efficiency when combined with a miRNA extraction solution. We suggest that the AGC device with an MPG membrane can be useful for the diagnosis and prognosis of serious illness using of EVs in various kinds of body fluids.

    The surface cation composition of nanoscale metal oxides critically determines the properties of various functional chemical processes including inhomogeneous catalysts and molecular sensors. Here we employ a gradual modulation of cation composition on a ZnO/(Cu1−xZnx)O heterostructured nanowire surface to study the effect of surface cation composition (Cu/Zn) on the adsorption and chemical transformation behaviors of volatile carbonyl compounds (nonanal: biomarker). Controlling cation diffusion at the ZnO(core)/CuO(shell) nanowire interface allows us to continuously manipulate the surface Cu/Zn ratio of ZnO/(Cu1−xZnx)O heterostructured nanowires, while keeping the nanowire morphology. We found that surface exposed copper significantly suppresses the adsorption of nonanal, which is not consistent with our initial expectation since the Lewis acidity of Cu2+is strong enough and comparable to that of Zn2+. In addition, an increase of the Cu/Zn ratio on the nanowire surface suppresses the aldol condensation reaction of nonanal. Surface spectroscopic analysis and theoretical simulations reveal that the nonanal molecules adsorbed at surface Cu2+sites are not activated, and a coordination-saturated in-plane square geometry of surface Cu2+is responsible for the observed weak molecular adsorption behaviors. This inactive surface Cu2+well explains the mechanism of suppressed surface aldol condensation reactions by preventing the neighboring of activated nonanal molecules. We apply this tailored cation composition surface for electrical molecular sensing of nonanal and successfully demonstrate the improvements of durability and recovery time as a consequence of controlled surface molecular behaviors.

    Electrical molecular nanosensors require two conflicting surface characteristics, which are catalytic activity for molecular selectivity and thermal stability for long-term data collection. Here, we show that a simple surface treatment using strong acids creates two such conflicting surface properties of WO3hydrate nanowires, which enhance the electrical molecular sensing of aldehydes (nonanal, a biomarker). Mass-spectrometric measurements reveal that the surface treatment using strong acids substantially promotes both the oxidization of nonanal and the desorption of products, nonanoic acid, from the surfaces at a temperature of 50 °C, which is lower than the 300 °C required for untreated surfaces. Spectroscopic and structural measurements combined with numerical simulations identify two different adsorption structures of carbonyl groups on the surface, where molecules directly bound to coordinatively unsaturated surface tungsten preferentially proceed to the catalytic oxidization reaction and the subsequent desorption process. Furthermore, we confirm the thermal durability (over 10 years) of the catalytic activity on acid-treated WO3hydrate nanowire surfaces up to 300 °C, which enables us to demonstrate the long-term stable sensor operations with the sensitivity (4 orders of magnitude) remaining for years.

    Measuring optically detected magnetic resonance (ODMR) of diamond nitrogen vacancy centers significantly depends on the photon detectors used. We study camera-based wide-field ODMR measurements to examine the performance in thermometry by comparing the results to those of the confocal-based ODMR detection. We show that the temperature sensitivity of the camera-based measurements can be as high as that of the confocal detection and that possible artifacts of the ODMR shift are produced owing to the complexity of the camera-based measurements. Although measurements from wide-field ODMR of nanodiamonds in living cells can provide temperature precisions consistent with those of confocal detection, the technique requires the integration of rapid ODMR measurement protocols for better precisions. Our results can aid the development of camera-based real-time large-area spin-based thermometry of living cells.

    Cancer-derived circulating exosomes or nanoscale extracellular vesicles are emerging biomarkers for disease detection and treatment because of their cell-specific constituents and unique intercellular pathways. For efficient exosome isolation from bio-fluids, the design of high-affinity nanointerfaces is of great importance in the development of miniaturized systems for the collection of exosomes. Herein, we report peptide-functionalized nanowires as a biorecognition interface for the capture and release of cancer-derived exosomes within a microfluidic channel. Based on the amino-acid sequence of EWI-2 protein, a partial peptide that bound to the CD9 exosome marker and thus targeted cancer exosomes was screened. Linkage of the exosome-targeting peptide with a ZnO-binding sequence allowed one-step and reagent-free peptide modification of the ZnO nanowire array. As a result of peptide functionalization, the exosome-capturing ability of ZnO nanowires was significantly improved. Furthermore, the captured exosomes could be subsequently released from the nanowires under a neutral salt condition for downstream applications. This engineered surface that enhances the nanowires' efficiency in selective and controllable collection of cancer-derived exosomes provides an alternative foundation for developing microfluidic platforms for exosome-based diagnostics and therapeutics.

    In this study, a facile, sensitive, and precise lab-on-a-chip electrophoretic method coupled with light-emitting diode induced fluorescence (LED-IF) detection was developed to assay three antiepileptic drugs, namely, vigabatrin, pregabalin, and gabapentin, in pharmaceutical formulations. The analytes were derivatised offline for the first time with fluorescine-5-isothiocyanate (FITC) to yield highly fluorescent derivatives with λex/em of 490/520 nm. The FITC-labelled analytes were injected, separated, and quantitated by a microfluidic electrophoresis device using fluorescence detection. The labelled analytes were monitored using a blue LED-IF system. The separation conditions were significantly optimised adding specific concentrations of heptakis-(2,6-di-O-methyl)-β-cyclodextrin (HDM-β-CD) and methylcellulose to the buffer solution (40 mM borate buffer). HDM-β-CD acted as a selective host for the studied antiepileptic drugs, rendering a high separation efficiency. Methylcellulose was used as an efficient dynamic coating polymer to prevent the labelled drugs from being adsorbed on the inner surfaces of the poly (methylmethacrylate) microchannels. A laboratory-prepared ternary mixture of the three antiepileptic drugs was separated within 100 s with acceptable resolution between all the three analytes (Rs > 3) and a high number of theoretical plates (N) for each analyte (N ≈ 106 plates/m). The sensitivity of the method was enhanced approximately 80-fold by stacking to yield a detection limit below 0.6 ng mL−1 in the concentration range of 2.0–200.0 ng mL−1. The method was successfully validated for analysing the studied drugs in their pharmaceutical formulations.

    Atomic layer deposition (ALD) is capable of providing an ultrathin layer on high-aspect ratio structures with good conformality and tunable film properties. In this research, we modified the surface of ZnO nanowires through ALD for the fabrication of a ZnO/SiO2 (core/shell) nanowire microfluidic device which we utilized for the capture of CpG-rich single-stranded DNAs (ssDNA). Structural changes of the nanowires while varying the number of ALD cycles were evaluated by statistical analysis and their relationship with the capture efficiency was investigated. We hypothesized that finding the optimum number of ALD cycles would be crucial to ensure adequate coating for successful tuning to the desired surface properties, besides promoting a sufficient trapping region with optimal spacing size for capturing the ssDNAs as the biomolecules traverse through the dispersed nanowires. Using the optimal condition, we achieved high capture efficiency of ssDNAs (86.7%) which showed good potential to be further extended for the analysis of CpG sites in cancer-related genes. This finding is beneficial to the future design of core/shell nanowires for capturing ssDNAs in biomedical applications. This journal is

    A green chiral lab-on-a-chip cyclodextrin-based microchip electrophoretic method was developed for enantioseparation of baclofen (BCN) and phenylalanine (Phe) enantiomers for the first time. All BCN and Phe enantiomers were offline labeled with 4-fluoro-7-nitrobenzofurazan (NBD-F) or fluorescein-5-isothiocyanate (FITC) fluorogenic reagents prior to microfluidic injection in a dynamically coated polymethylmethacrylate microchip. The enantioseparation was performed using borate buffer solution (50 mM; pH 9.5) containing a dynamic coating polymer (methylcellulose) and a chiral selector of cyclodextrin (CD) family as the background electrolyte. The combination of sieving properties of methylcellulose polymer and inclusion complex formation properties of the cyclodextrins rendered a novel green pseudo-stationary phase for the microfluidic chiral separation of the studied enantiomers in short separation time. Seven CD chiral selectors were investigated in our study to illustrate the proposed enantioseparation mechanism in the dynamically coated microfluidic channels. The results indicated that use of a modified cyclodextrin, heptakis-(2,6-di-O-methyl)-β-cyclodextrin (HDM-β-CD), resulted in extra interactions with the analytes of interest, leading to extra resolution with high number of theoretical plates. Therefore, HDM-β-CD was able to separate the NBD-labeled and FITC-labeled enantiomers of BCN and Phe within short analytical time. Sensitivity problem of microchip electrophoresis was overcome by application of field-enhanced injection stacking which improved sensitivity to a higher extent by online preconcentration of the labeled enantiomers in the microfluidic channels. The method was fully validated and successfully applied for the assay of BCN enantiomers and Phe enantiomers in their pure racemic mixtures. Moreover, the developed method was applied for precise analysis of BCN enantiomers in pharmaceutical formulations and in biological samples. The extraction recovery values of BCN enantiomers in biological samples were > 87.5% and %RSD < 7.0.

    Liquid biopsy is a method that is expected to be able to detect and track the cancers using blood, urine, saliva and other body fluids. The advantages of liquid biopsy are that it is extremely minimally invasive compared to tissue biopsies, and that it is easy to perform the repeated and frequent tests that are necessary for long―term tracking. Recently, extracellular vesicles(EVs) have been added to the list of biological materials to be analyzed by liquid biopsy. In this paper, we introduce the comprehensive analysis of microRNAs contained in EVs in urine using nanowire devices and AI, and its application to cancer detection.

In order to enhance the safety and treatment effect of regenerative medicine, it is necessary to understand where transplanted cells accumulate in the tissue and how the accumulated cells behave in tissues and organs at a cell level. In this study, we challenged the innovative diagnosis of transplanted islet cells in the liver of mice by advanced technologies such as fluorescence imaging using "quantum dots (QDs)" and whole tissue clearing using "clear, unobstructed brain/body imaging cocktails and computational analysis (CUBIC)". After transplantation of islet cells labeled with QDs800 into the living body of the nude mice through portal vein, it was confirmed that the transplanted islet cells were mainly accumulated in the liver of the mice after 10 min. of transplantation using <i>in vivo</i> imaging system.

    To investigate the effect of the network structure on the mechanical properties of a polymer network formed from a certain polymer, we should prepare polymer networks with clearly different network structures made of the same polymer and compare the mechanical properties of these polymer networks. If a living radical polymerization method is applied to the same monomer constituting the polymer network with a nonuniform network structure obtained by conventional free-radical polymerization, it is possible to obtain a polymer network with a uniform network structure in which the molecular weights of the polymer chains bonded to the cross-linking points are uniform and the number of chains bonded to the cross-linking points is constant. In this study, we worked on the synthesis of a polymer network with a uniform network structure by combining two different types of star-shaped polymer synthesis methods using living radical polymerization, i.e., the core-first method and the linking method. In the core-first method, it was possible to synthesize a star-shaped polymer with a narrow molecular weight distribution in a state with a molecular weight corresponding to the charging ratio of the initiator with four initial groups and the monomer. We confirmed that the polymer network obtained by binding the star-shaped polymers by the linking method had a uniform structure, even when swollen with a good solvent or dried, from small-angle X-ray scattering. Depending on the molecular weight of the star-shaped polymer obtained by the core-first method and the amount of the cross-linking agent added for the linking method, the mesh size of the network could be changed while having a uniform network structure. The dried polymer network with uniform network structures exhibited significantly higher values of fracture extensibility and energy than those with nonuniform network structures via conventional free-radical polymerization, when compared at the same monomer and cross-linker concentration.

    The variability of bioparticles remains a key barrier to realizing the competent potential of nanoscale detection into a digital diagnosis of an extraneous object that causes an infectious disease. Here, we report label-free virus identification based on machine-learning classification. Single virus particles were detected using nanopores, and resistive-pulse waveforms were analyzed multilaterally using artificial intelligence. In the discrimination, over 99% accuracy for five different virus species was demonstrated. This advance is accessed through the classification of virus-derived ionic current signal patterns reflecting their intrinsic physical properties in a high-dimensional feature space. Moreover, consideration of viral similarity based on the accuracies indicates the contributing factors in the recognitions. The present findings offer the prospect of a novel surveillance system applicable to detection of multiple viruses including new strains.

    Recent studies on nanopillar arrays, one type of nanofluidic device, have demonstrated various tools for bioanalysis. When carrying out nanopillar array-based separation, it is indispensable to observe biomolecules, such as DNA, proteins, and extracellular vesicles, that have fluorescence labeling; however, fluorescence labeling influences the biomolecular characteristics. Here, we have proposed label-free monitoring of biomolecule separation by using diffracted light derived from the nanopillar array that was fabricated inside a microchannel by combining laser interference lithography with general photolithography techniques. Using an electrophoresis approach, we demonstrated that our diffraction-based label-free method possessed high sensor initialization ability, and the nanopillar array device successfully monitored DNA separation without labeling bias. Results obtained using our label-free monitoring of DNA separation confirmed, for the first time, that the molecular dynamics of DNA molecules in the nanopillar array were changed in the presence or absence of fluorescent labeling. The presented concept will provide a useful tool for nonbiased monitoring of label-free biomolecule analysis in nanofluidic channels.

    Ammonia is a well-known additive to promote crystal growth in hydrothermal synthesis of ZnO nanowires. Although the effect of ammonia on the nanowire growth has been intensively investigated, its influence on the seed layer, which governs the initial nanowire growth, is rarely discussed. Here, we demonstrate that ammonia strongly affects the seed layer as well as the following nanowire growth. On increasing the ammonia concentration, the nanowire density first increases and then decreases, while the nanowire growth rate keeps increasing. Experimental results and thermodynamic calculations of the initial growth process reveal that the transformation of the seed layer induced by ammonia prior to nucleation critically determines the nanowire density and thus also influences the following nanowire growth. Present results highlight the critical importance of discussing the variation of seed layers in ammonia-involved hydrothermal synthesis and suggest a novel seed engineering approach for tailoring the ZnO nanowire growth.

    Tailoring the elemental doping of inorganic nanowires remains an important challenge due to complex dopant incorporation pathways. Here we report that the face-selectivity of tungstate ions controls growth direction and dopant incorporation of hydrothermal zinc oxide nanowires. The introduction of tungstate ions on nanowire surface during synthesis unexpectedly enhances nucleation at sidewall <mml:mfenced close="}" open="{">101<mml:mo><overbar></mml:mover>0</mml:mfenced> planes, while dopant incorporation occurs only on (0001) planes. This conflicting face-selective behavior leads to inhomogeneous dopant distribution. Density functional theory calculations reveal that the face-selective behavior can be interpreted in terms of the effect of coordination structure of the tungstate ions on each zinc oxide crystal plane. In addition, we demonstrate a rational strategy to control the morphology and the elemental doping of tungsten-doped zinc oxide nanowires. Controlling the growth processes of nanowires is vital for tailoring their properties. Here, the presence of tungstate ions on specific surface planes of zinc oxide nanowires causes nanowire growth and chemical doping along specific crystal planes.

    There are growing interests in mechanical rupture-based antibacterial surfaces with nanostructures that have little toxicity to cells around the surfaces; however, current surfaces are fabricated via top-down nanotechnologies, which presents difficulties to apply for bio-surfaces with hierarchal three-dimensional structures. Herein, we developed ZnO/SiO2 nanowire structures by using bottom-up approaches and demonstrated to show mechanical rupture-based antibacterial activity and compatibility with human cells. When Escherichia coli were cultured on the surface for 24 h, over 99% of the bacteria were inactivated, while more than 80% of HeLa cells that were cultured on the surface for 24 h were still alive. This is the first demonstration of mechanical rupture-based bacterial rupture via the hydrothermally synthesized nanowire structures with antibacterial activity and cell compatibility.

    Intracellular thermometry techniques play an important role in elucidating the relationship between the intracellular temperature and stem cell functions. However, there have been few reports on thermometry techniques that can detect the intracellular temperature of cells during several days of incubation. In this study, we developed a novel quantum thermometric sensing and analysis system (QTAS) using fluorescent nanodiamonds (FNDs). FNDs could label adipose tissue-derived stem cells (ASCs) at high efficiency with 24 h of incubation, and no cytotoxicity was observed in ASCs labeled with less than 500 μg mL−1of FNDs. The peak of FNDs was confirmed at approximately 2.87 GHz with the characteristic fluorescence spectra of NV centers that could be optically detected (optically detected magnetic resonance [ODMR]). The ODMR peak clearly shifted to the high-frequency side as the temperature decreased and gave a mean temperature dependence of −(77.6 ± 11.0) kHz °C−1, thus the intracellular temperature of living ASCs during several days of culturing could be precisely measured using the QTAS. Moreover, the intracellular temperature was found to influence the production of growth factors and the degree of differentiation into adipocytes and osteocytes. These data suggest that the QTAS can be used to investigate the relationship between intracellular temperature and cellular functions.

    Multinary semiconductor quantum dots (QDs) that have less toxicity and show near-infrared light responsivity have attracted much attention for in vivo bioimaging. In this study, we controlled the optical properties of Ag-In-Se QDs by modulating the nonstoichiometry and the degree of Ga3+ doping. Precise tuning of the Ag/In ratio of Ag-In-Se QDs enabled a sharp band-edge emission to emerge without broad defect-site emission. Ga3+ doping into Ag-In-Se (AIGSe) QDs enlarged their energy gap, resulting in a blue shift of the band-edge PL peak from from 890 to 630 nm. The band-edge PL intensity was remarkably enlarged by surface coating with a thin GaSx shell followed by treatment with trioctylphosphine, the highest PL yield being 38% for the PL peak at 800 nm. Thus-obtained QDs were successfully used as near-IR PL probes for three-dimensional in vivo bioimaging in which the wavelengths of excitation and detection lights could be selected in the first biological window, and then the signals were clearly detected from AIGSe@GaSx core-shell QDs injected into biological tissues by ca. 5 mm in depth.

    Background: Small cell lung cancer (SCLC) has a poor prognosis, and its treatment options are limited. Delta-like protein 3 (DLL3) is expressed specifically in SCLC and is considered a promising therapeutic target for patients with this disease. Rovalpituzumab tesirine (Rova-T) was the first antibody-drug conjugate targeting DLL3. Although Rova-T development was unfortunately terminated, DLL3 remains an ideal target for SCLC. Near infrared photoimmunotherapy (NIR-PIT) is a new form of cancer treatment that employs an antibody-photosensitiser conjugate followed by NIR light exposure and damage target cells specifically. In this study, we demonstrate DLL3-targeted NIR-PIT to develop a novel molecularly targeted treatment for SCLC. Methods: The anti-DLL3 monoclonal antibody rovalpituzumab was conjugated to an IR700 photosensitiser (termed ‘rova-IR700’). SCLC cells overexpressing DLL3 as well as non-DLL3-expressing controls were incubated with rova-IR700 and then exposed to NIR-light. Next, mice with SCLC xenografts were injected with rova-IR700 and irradiated with NIR-light. Findings: DLL3-overexpressing cells underwent immediate destruction upon NIR-light exposure, whereas the control cells remained intact. The xenograft in mice treated with rova-IR700 and NIR-light shrank markedly, whereas neither rova-IR700 injection nor NIR-light irradiation alone affected tumour size. Interpretation: Our data suggest that targeting of DLL3 using NIR-PIT could be a novel and promising treatment for SCLC.

    <p>It has become clear that temperature plays a major role in many life phenomena. However, little is known about the intracellular temperature, and the relationship between regenerative function and intracellular temperature of stem cells. In this study, fluorescent nanodiamond (FND) that can be applied as an excellent quantum sensor was used for stem cell labeling. Then, the relationship between the regenerative function of stem cells and the intracellular temperature of stem cells was evaluated by a sensing the optically detected magnetic resonance (ODMR) activity of NV centers in FNDs. FNDs could label adipose tissue-derived stem cells (ASCs) at high efficiency with 24 h incubation, and no cytotoxicity was observed in ASCs labeled with less than 500 µg/mL of FNDs. The ODMR of NV centers in FNDs was confirmed at approximately 2.87 GHz with a characteristic fluorescence spectrum, and the intracellular temperature of living ASCs during several days of culturing could be precisely measured. Moreover, the intracellular temperature was found to influence the production of growth factors and the degree of differentiation into adipocytes and osteocytes. These data suggest that NV centers in FNDs can be used to investigate the relationship between intracellular temperature and cellular functions.</p>

    Detecting molecular targets in specimens from patients with lung cancer is essential for targeted therapy. Recently, we developed a highly sensitive, rapid-detection device (an immuno-wall device) that utilizes photoreactive polyvinyl alcohol immobilized with antibodies against a target protein via a streptavidin–biotin interaction. To evaluate its performance, we assayed epidermal growth factor receptor (EGFR) mutations, such as E746_A750 deletion in exon 19 or L858R substitution in exon 21, both of which are common in non-small cell lung cancer and important predictors of the treatment efficacy of EGFR tyrosine kinase inhibitors. The results showed that in 20-min assays, the devices detected as few as 1% (E746_A750 deletion) and 0.1% (L858R substitution) of mutant cells. Subsequent evaluation of detection of the mutations in surgically resected lung cancer specimens from patients with or without EGFR mutations and previously diagnosed using commercially available, clinically approved genotyping assays revealed diagnostic sensitivities of the immuno-wall device for E746_A750 deletion and L858R substitution of 85.7% and 87.5%, respectively, with specificities of 100% for both mutations. These results suggest that the immuno-wall device represents a good candidate next-generation diagnostic tool, especially for screening of EGFR mutations.

    Fine particulate matter sized 2.5 μm or less, referred to as PM2.5, causes serious air pollution in urban cities and is responsible for several health problems, such as respiratory disease and asthma in urban populations. Although seasonal Asian dust, called Kosa (~ 5 μm), has been extensively studied for over decades, and has been shown to be an allergen in Japan, the influence of PM2.5 on human health has remained unclear due to the intrinsic chemical and biological complexity of isolating variables for study. In this study, PM2.5 was collected at Ito Campus in Kyushu University, Fukuoka, located in extreme western Japan and its physical and biological characteristics were analyzed. The presence of bacteria, Firmicutes genus Bacillus, Lysinibacillus, Paenibacillus, Gracilibacillus, and Solibacillus in the collected PM2.5 sample was confirmed by culturing and conducting DNA sequencing of their 16S rRNA gene.

    Toward evaluating health risk of particulate matter with size less than or equal to 2.5 μm (PM2.5), we propose a methodology for realizing the PM2.5 analysis in liquid phase via water film-based collection and microfluidics-based electrical detection. We reported last year that a hydrophilic nanowire surface was utilized in the collection for formation of a water film, which enabled continuous collection of air-floating PM2.5 into liquid phase and followed-by detection. As advanced results, the collected PM2.5 was successfully detected and analyzed via ion current sensing using a micropore. We believe proposed PM2.5 analysis methodology in liquid phase would allow to realize health risk evaluation and reduce health damage.

    <p>幹細胞移植は幹細胞をそのまま、あるいは前駆細胞に分化させた状態で血流に乗せて移植する治療法であり、幹細胞を用いた組織や臓器の再構築が未だ困難とされている疾病に対して有効な治療法であるとして近年注目を集めている。幹細胞移植の実現に向けては、安全性が十分に確保されており、尚且つ治療効果が大きい移植プロトコールを確立する必要があり、この課題の解決に向けて、移植幹細胞の体内動態や生着部位を高感度にイメージングし、どのように治療効果を発揮しているかを解明する必要がある。しかし、これまで生体内のすべての移植幹細胞を網羅的にイメージング診断できる技術は確立されていない。臓器や組織は光を吸収・散乱する様々な物質から構成されており、光の透過性が極めて低いため、二光子励起顕微鏡などを用いても表面上のしかも限られた視野での観察に留まっているのが現状である。そこで我々は、臓器の効率的な透明化が可能な技術に注目し量子ドットを用いた幹細胞蛍光イメージング技術と融合することで、急性肝不全モデルマウスにおける移植幹細胞の網羅的、且つ単一細胞レベルの解像度でのイメージングを可能にする革新的診断技術の確立に取り組んだ。</p>

    <p>幹細胞による再生治療メカニズム解明は、再生医療の更なる安全性、治療効果向上において極めて重要である。幹細胞は自己複製能と多分化能を持つ特殊な細胞であり、障害部位への特異的な集積能力や再生因子産性能を持つことから患者に移植することで治療効果を発揮することが知られている。更に、近年では幹細胞から放出されるエクソソームも同様に治療効果を持つことがわかっており、新規治療ツールとして注目され始めている。しかし、エクソソームの詳細な生体内挙動及び細胞間移動等について解析できる技術が乏しく、再生機能の役割については未だ未解明のままである。本研究では、エクソソームを生体内で高感度に検出できる技術の確立を目指した。最先端量子ナノ材料である量子ドットをグルコース修飾することで、もともと細胞が持つグルコーストランスポーターを通して細胞内に導入することに成功した。また、グルコーストランスポーターを持つとされるエクソソームにおいても同様に内部への導入が確認された。エクソソームの内部に導入することで、膜上に蛍光色素を付着させる従来法に比べてより安定で高感度のラベル化に成功した。</p>

    © 2019 CBMS-0001. Peptides optimally binding to solid surfaces are a promising candidate for adding bio-affinity, however, their binding states are not fully revealed. Herein, we realized a methodology for analyzing peptide adsorption states via employing nanowires and infrared (IR) p-polarized multiple-angle incidence resolution spectrometry (pMAIRS). Our methodology enabled to provide large crystalline surface for peptide adsorption, and enhance signal intensities. We found that a modelled peptide had different adsorption states among crystal axes. Analyzing peptide adsorption states can pave the way for controlling adsorbed states, and moreover, using full potentials of peptide.

    © 2019 CBMS-0001. Analyzing microRNAs in our body allowed us to investigate our various vital in Here [1], our aim is that discovering additional vital information based on microRNAs from saliva samples. MicroRNAs in body fluids are known to obtain higher stability in body fluids via encapsulation in extracellular vesicles with over 40-nm diameter [2]. To capture the vesicles, we conceived an idea to use nanocellulose with several 10- to several 100-nm pore sizes. The nanocellulose made it possible to extract over 1000 species of microRNAs from 10 µL saliva within 20 s, compared to ultracentrifugation, which required over 180 min and 10 µL saliva to extract around 600 species of microRNAs.

    A fluoropolymer membrane filter with through-holes was fabricated by photolithographic patterning and the dry etching method. 380,000 highly packed through-holes, each with a diameter of 7 µm were able to cover a whole area with a diameter of 13 mm. Ethylene tetrafluoroethylene (ETFE) was used as the membrane, which was suitable for the fluorescence detection of rare cells such as circulating tumor cells (CTCs) in human blood. The device fabrication for the size based capture of rare cells in blood such as CTCs is realized in this study.

    Quantum dots (QDs) have excellent fluorescence properties in comparison to traditional fluorescence probes. Thus, the optical application of QDs is rapidly expanding to each field of analytical chemistry. In this review paper, we reviewed the application of QDs to regenerative medicine, especially stem cell transplantation therapy. The labeling of stem cells using QDs composed of semiconductor materials in combination with a chemical substance, poly-cationic liposome and cell penetrating peptide is reported. In addition, the influence of QD labeling on the pluripotency of stem cells is also reported. Finally, the in vivo imaging of transplanted stem cells in mice by QDs emitting fluorescence in the near-infrared region, which can be detected by in vivo fluorescence imaging systems such as IVIS and SAI-1000, is described. The future prospects for stem cell imaging technology by QDs are also discussed.

    <jats:p>Quantum dots (QDs) are powerful luminescent probes for detecting single-molecules and imaging live cells. Despite several reports on bioimaging and biosensing applications of QDs, controlled and targeted detection of biomolecules using quantum dots is an ongoing challenge. When a QD is conjugated with an ideal chromophore, which can be a fluorescent or a non-fluorescent dye molecule, QD luminescence can be quenched by Förster resonance energy transfer (FRET) to the quencher dye. However, the photoluminescence of QD can be recovered upon on-demand release of the quencher. Our study focuses on quenching of QD photoluminescence after conjugation with a non-fluorescent dye molecule, black hole quencher 1 (BHQ-1), intermediated with a molecular sensing target peptide GPLG↓VRGK. Based on steady-state and time-resolved photoluminescence measurements of QD and the QD-peptide-BHQ-1 sensor assemblies, we attribute the quenching of photoluminescence intensity and lifetime to FRET from the QD to BHQ-1molecules. Here the intermediate peptide GPLG↓VRGK can be cleaved by matrix metalloproteinase-2 (MMP-2), an enzyme that is upregulated in cancer cells extra cellular matrix (ECM), at its Gly and Val region shown by the down headed arrow. Here the QD-pep-BHQ-1 conjugate detected the MMP-2 presence at the extra cellular matrix of H1299 cancer cells. Further the QD-pep-BHQ-1 molecules were conjugated at the surface of a mesoporous silica nanoparticle (MSN) scaffold to localize maximum target peptide in a nanospace volume for the future αvβ3 integrin receptor targeted detection of MMP-2. The luminescence quenching of MSN-QD-pep-BHQ-1 conjugates were analyzed with time resolved photoluminescence measurement.</jats:p>

    We have demonstrated a PM 2.5 analysis method that adds information on the number concentration and size by using microfluidic-based ionic current sensing with a bridge circuit. The bridge circuit allows for suppression of the background current and the detection of small PM 2.5 particles, even if a relatively large micropore is used. This is the first demonstration of the detection of PM 2.5 particles via ionic current sensing; our method enables analyses of both the number concentration and size.

    Copyright© (2018) by Chemical and Biological Microsystems Society.All rights reserved. In this study, we have developed ionic current detection device that can discriminate cells by measurement of cell deformability for detecting circulating tumor cells (CTC). We successfully discriminated CTC model from leukocyte model without any fluorescent labels by using the device. Moreover, we could detect relatively small CTCs compared to blood cells, which are difficult to detect by conventional filter devices. This device is expected as a new cancer diagnostic device that is simple and highly sensitive.

We present a study of centrifugal filtration device toward easy-to-use approach of non-invasive liquid biopsy for cancer diagnosis by cell-derived nanoscale vesicles (exosomes). A phase-dispersed glass filter having nanoporous structure was embedded into a spin column to trap exosomes with small centrifuge. This device enabled over 90% exosome isolation from biological samples within 10 minutes.

    Copyright © (2018) by Chemical and Biological Microsystems Society. All rights reserved. Detecting of cell-free circulating methylated DNA could be a promising method for early diagnosis of cancer. Here we have developed the microheater - zinc oxide nanowires (ZnO-NWs) structures embedded in the microchannel device for capturing DNA via electrostatic interaction. We found that 60% of DNA could be captured on ZnO-NWs. Additionally, the microheater, which constantly enables to generate heat, can denature double stranded DNA (dsDNA) to single stranded DNA (ssDNA). Finally, ICON Probe, which is an artificial ssDNA probe for DNA methylation, was introduced inside a device to bind to ssDNA for DNA methylation detection.

    Copyright © (2018) by Chemical and Biological Microsystems Society. All rights reserved. Molecular recognition methods such as those found in antigen-antibody reactions are attracting attention. We demonstrated more selective molecular recognition through focusing on not only intermolecular interaction but also the shape of the molecules. Here, we fabricated molecular shapes of aniline on the titanium oxide thin film on the core-shell structure of zinc oxide/titanium oxide nanowires, and recognized aniline, selectively, using the aniline molecular shaped nanowires.

    Copyright© (2018) by Chemical and Biological Microsystems Society.All rights reserved. Toward evaluation of health risk of particulate matter with size less than or equal to 2.5 µm (PM2.5), we propose a methodology for realizing the PM2.5 analysis in liquid phase via water film-based collection and microfluidics-based electrical detection. A hydrophilic nanowire surface was utilized in the collection for forming a water film, which enabled continuous collection of air-floating PM2.5 into liquid phase and followed-by detection. The collected PM2.5 was electrically detected and analyzed via ionic current sensing with a micropore. We believe proposed PM2.5 analysis methodology in liquid phase would allow to realize health risk evaluation and reduce health damage.

    Here, we developed a device integrated with a nanochannel and nanostructures to slow DNA translocation velocity. We found that translocation velocity of a single DNA molecule inside a nanochannel was decreased by pre-elongating it using some nanostructures, such as a shallow channel or nanopillars. This decrease of the translocation velocity was associated with the DNA mobility change, which is an intrinsic parameter of DNA molecules and unaffected by an electric field.

    The steady state and time-resolved photoluminescence quenching of streptavidin modified CdSe/ZnS quantum dots (QDs) instigated by biotin-peptide-BHQ-1 (biotin-pep-BHQ-1) molecule was investigated. Here, we have achieved an efficient photoluminescence (PL) quenching of QDs with the conjugation of dark quencher (black hole quencher-BHQ) molecules intermediated with the GPLGVRGK peptide. The luminescence of streptavidin-QDs585 was decreased upon titration with a nano molar concentration of the biotin-GPLGVRGK-BHQ-1 molecule. It has been suggested that the decrease of QDs PL occurred through a Förster resonance energy transfer (FRET) mechanism from the analysis of steady state photoluminescence intensity measurements as well as time resolved lifetime measurements of streptavidin-QDs and QDs- (pep-BHQ-1) n conjugates. The sequence of intermediate peptide GPLG↓VRGK can act as a target material for matrix metalloproteinases-2 (MMP-2) produced by cancer cells at its Gly and Val region, shown by the down-headed arrow. Interestingly, here the reported self-assembled QDs-(pep-BHQ-1) n conjugates could detect the presence MMP-2 at a detection limit of 1 ng/mL with a clear luminescence recovery.

    We investigated the transduction function of a cationic dextran hydroxypropyltrimethyl ammonium chloride-coated magnetic iron oxide nanoparticle (TMADM-03) for transducing quantum dots (QDs) into adipose tissue-derived stem cells (ASCs). As a result, the fluorescence intensity of ASCs labeled with QDs using TMADM-03 was much higher than that of QDs only labeling. These data suggest that TMADM-03 can be useful as a transduction agent for QDs in stem-cell imaging.

    Here, we report the effect of DNA methylation on the velocity of DNA translocation through a nanochannel, as determined by measuring differences in translocation velocities between methylated and non-methylated DNA molecules. We found that the velocity of translocation of methylated DNA was faster than that of non-methylated DNA, which we attributed to variation in the coefficients of diffusion and friction with the nanochannel wall, due to the increased molecular weight and stiffness, respectively, of methylated DNA.

    Here, we developed a device integrated with a nanochannel and nanostructures to slow DNA translocation velocity. We found that translocation velocity of a single DNA molecule inside a nanochannel was decreased by pre-elongating it using some nanostructures, such as a shallow channel or nanopillars. This decrease of the translocation velocity was associated with the DNA mobility change, which is an intrinsic parameter of DNA molecules and unaffected by an electric field.

    Quantum dots (QDs) have excellent fluorescence properties in comparison to traditional fluorescence probes. Thus, the optical application of QDs is in rapid expansion to each field of analytical chemistry. In this paper, we described about the application of QDs to regenerative medicine, especially stem cell transplantation therapy. Specifically, labeling technologies of stem cells by QDs composed of semiconductor materials in combination with poly-cationic liposome (Lipofectamine<sup>&reg;</sup>) or cell penetrating peptide (octa-arginine) were reviewed. Moreover, <i>in vivo</i> imaging of transplanted stem cells in mice by QDs emitting fluorescence in near-infrared region, which could be detected by fluorescence <i>in vivo</i> imaging machines such as IVIS imaging system, was reported.

    In the field of microfluidics, it is possible to facilitate liquid transport through microsized holes with large slip lengths by lowering the friction at the interface between the flow and the inner surface of the holes. In this paper, we discuss the use of nonequilibrium atmospheric-pressure plasma to modify the surface wettability of microsized holes in glass substrates that are similar to those used as flow channels in glass microfiltration devices. In our experiments, liquid transport flows were driven by internal Laplace pressure differences based on the surface tensions of droplets placed on the front and back sides of the tested substrates.

    Comprehensive imaging of a biological individual can be achieved by utilizing the variation in spatial resolution, the scale of cathodoluminescence (CL), and near-infrared (NIR), as favored by imaging probe Gd2O3 co-doped lanthanide nanophosphors (NPPs). A series of Gd2O3:Ln3+/Yb3+ (Ln3+: Tm3+, Ho3+, Er3+) NPPs with multispectral emission are prepared by the sol-gel method. The NPPs show a wide range of emissions spanning from the visible to the NIR region under 980 nm excitation. The dependence of the upconverting (UC)/downconverting (DC) emission intensity on the dopant ratio is investigated. The optimum ratios of dopants obtained for emissions in the NIR regions at 810 nm, 1200 nm, and 1530 nm are applied to produce nanoparticles by the homogeneous precipitation (HP) method. The nanoparticles produced from the HP method are used to investigate the dual NIR and CL imaging modalities. The results indicate the possibility of using Gd2O3 co-doped Ln3+/Yb3+ (Ln3+: Tm3+, Ho3+, Er3+) in correlation with NIR and CL imaging. The use of Gd2O3 promises an extension of the object dimension to the whole-body level by employing magnetic resonance imaging (MRI).

    We investigated an anomalous DNA separation where two DNA fragments from the human Y-chromosome sY638 (64 bp) and sY592 (65 bp), with only one base pair difference, were separated. This result is abnormal since in a previous study, we found that 5 bp was the minimum difference between two DNA fragments that the microchip electrophoresis system can separate. The formation of a mini-loop in the structure of the DNA fragment of sY638 (64 bp) was strongly expected to be the reason. To investigate this, we synthesized three modified DNA fragments for sY638 (64 bp), and the modifications were in two expected locations for possible mini-loop formation. Later, the separation between sY592 (65 bp) and the three modified fragments of sY638 (64 bp) was not possible. Thus, we conclude that the formation of a mini-loop in the structure of the DNA is the reason behind this anomalous separation.

    Quantitative DNA amplification using fluorescence labeling has played an important role in the recent, rapid progress of basic medical and molecular biological research. Here we report a label-free detection of real-time DNA amplification using a nanofluidic diffraction grating. Our detection system observed intensity changes during DNA amplification of diffracted light derived from the passage of a laser beam through nanochannels embedded in a microchannel. Numerical simulations revealed that the diffracted light intensity change in the nanofluidic diffraction grating was attributed to the change of refractive index. We showed the first case reported to date for label-free detection of real-time DNA amplification, such as specific DNA sequences from tubercle bacilli (TB) and human papillomavirus (HPV). Since our developed system allows quantification of the initial concentration of amplified DNA molecules ranging from 1 fM to 1 pM, we expect that it will offer a new strategy for developing fundamental techniques of medical applications.

    Dry eye is a problem in tearing quality and/or quantity and it afflicts millions of persons worldwide. An autologous serum eye-drop is a good candidate for dry eye treatment; however, the eye-drop preparation procedures take a long time and are relatively troublesome. Here we use spiral microchannels to demonstrate a strategy for the preparation of autologous serum eye-drops, which provide benefits for all dry eye patients; 100% and 90% removal efficiencies are achieved for 10 μm microbeads and whole human blood cells, respectively. Since our strategy allows researchers to integrate other functional microchannels into one device, such a microfluidic device will be able to offer a new one-step preparation system for autologous serum eye-drops.

    Accurate, sensitive, rapid, and easy operative diagnosis is necessary to prevent the spread of malaria. A cell microarray chip system including a push column for the recovery of erythrocytes and a fluorescence detector was employed for malaria diagnosis in Uganda. The chip with 20,944 microchambers (105 μm width and 50 μm depth) was made of polystyrene. For the analysis, 6 μl of whole blood was employed, and leukocytes were practically removed by filtration through SiO 2 -nano-fibers in a column. Regular formation of an erythrocyte monolayer in each microchamber was observed following dispersion of an erythrocyte suspension in a nuclear staining dye, SYTO 21, onto the chip surface and washing. About 500,000 erythrocytes were analyzed in a total of 4675 microchambers, and malaria parasite-infected erythrocytes could be detected in 5 min by using the fluorescence detector. The percentage of infected erythrocytes in each of 41 patients was determined. Accurate and quantitative detection of the parasites could be performed. A good correlation between examinations via optical microscopy and by our chip system was demonstrated over the parasitemia range of 0.0039-2.3438% by linear regression analysis (R 2 =0.9945). Thus, we showed the potential of this chip system for the diagnosis of malaria.

    This paper presents a new correlative bioimaging technique using Y2O3:Tm, Yb and Y2O3:Er, Yb nanophosphors (NPs) as imaging probes that emit luminescence excited by both near-infrared (NIR) light and an electron beam. Under 980 nm NIR light irradiation, the Y2O3:Tm, Yb and Y2O3:Er, Yb NPs emitted NIR luminescence (NIRL) around 810 nm and 1530 nm, respectively, and cathodoluminescence at 455 nm and 660 nm under excitation of accelerated electrons, respectively. Multimodalities of the NPs were confirmed in correlative NIRL/CL imaging and their locations were visualized at the same observation area in both NIRL and CL images. Using CL microscopy, the NPs were visualized at the single-particle level and with multicolour. Multiscale NIRL/CL bioimaging was demonstrated through in vivo and in vitro NIRL deep-tissue observations, cellular NIRL imaging, and high-spatial resolution CL imaging of the NPs inside cells. The location of a cell sheet transplanted onto the back muscle fascia of a hairy rat was visualized through NIRL imaging of the Y2O3:Er, Yb NPs. Accurate positions of cells through the thickness (1.5 mm) of a tissue phantom were detected by NIRL from the Y2O3:Tm, Yb NPs. Further, locations of the two types of NPs inside cells were observed using CL microscopy.

    Because nanoparticles with diameters less than 50 nm penetrate stromal-rich tumor tissues more efficiently, the synthesis of small-sized nanoparticles encapsulating short interfering RNA (siRNA) is important in terms of realizing novel siRNA medicine for the treatment of various cancers. Lipid nanoparticles (LNPs) are the leading systems for the delivery of siRNA in vivo. Limit size LNPs were successfully synthesized using a microfluidic mixing technique. However, the physicochemical properties and potential for in vivo siRNA delivery of the limit-size LNPs have not been examined in detail. In the present study, we prepared LNPs with different diameters from 32 to 67 nm using a microfluidic mixing devise and examined the physicochemical properties of the particles and the potential for their use in delivering siRNA in vitro and in vivo to liver. Reducing the size of the LNPs causes poor-packing and an increased surface area, which result in their instability in serum. Moreover, it was revealed that the ability of endosomal escape (cytosolic siRNA release) of the smaller LNPs is subject to inhibition by serum compared to that of larger counterparts. Taken together, an increase in packing and avoiding the adsorption of serum components are key strategies for the development of next-generation highly potent and small-sized LNPs.

    This review highlights the most promising applications of nanowires for bioanalytical chemistry and medical diagnostics. The materials discussed here are metal oxide and Si semiconductors, which are integrated with various microfluidic systems. Nanowire structures offer desirable advantages such as a very small diameter size with a high aspect ratio and a high surface-to-volume ratio without grain boundaries; consequently, nanowires are promising tools to study biological systems. This review starts with the integration of nanowire structures into microfluidic systems, followed by the discussion of the advantages of nanowire structures in the separation, manipulation and purification of biomolecules (DNA, RNA and proteins). Next, some representative nanowire devices are introduced for biosensors from molecular to cellular levels based on electrical and optical approaches. Finally, we conclude the review by highlighting some bio-applications for nanowires and presenting the next challenges that must be overcome to improve the capabilities of nanowire structures for biological and medical systems.

    World Health Organization grade II and III gliomas most frequently occur in the central nervous system (CNS) in adults. Gliomas are not circumscribed; tumor edges are irregular and consist of tumor cells, normal brain tissue, and hyperplastic reactive glial cells. Therefore, the tumors are not fully resectable, resulting in recurrence, malignant progression, and eventual death. Approximately 69–80% of grade II and III gliomas harbor mutations in the isocitrate dehydrogenase 1 gene (IDH1), of which 83–90% are found to be the IDH1-R132H mutation. Detection of the IDH1-R132H mutation should help in the differential diagnosis of grade II and III gliomas from other types of CNS tumors and help determine the boundary between the tumor and normal brain tissue. In this study, we established a highly sensitive antibody-based device, referred to as the immuno-wall, to detect the IDH1-R132H mutation in gliomas. The immuno-wall causes an immunoreaction in microchannels fabricated using a photo-polymerizing polymer. This microdevice enables the analysis of the IDH1 status with a small sample within 15 min with substantially high sensitivity. Our results suggested that 10% content of the IDH1-R132H mutation in a sample of 0.33 μl volume, with 500 ng protein, or from 500 cells is theoretically sufficient for the analysis. The immuno-wall device will enable the rapid and highly sensitive detection of the IDH1-R132H mutation in routine clinical practice.

    A novel capillary electrophoretic method was developed for the assay of two quaternary anti-Parkinson mixtures, entacapone, levodopa, carbidopa, and benserazide (mixture I), and selegiline, levodopa, carbidopa, and benserazide (mixture II), by using α-methyldopa as an internal standard. Furthermore, the method was extended for the determination of another anti-Parkinson drug, lisuride, as well as a psychoactive antihypertensive drug, α-methyldopa, without any modification of the general method. Separation and analyses of all compounds were simply achieved in an untreated fused-silica capillary tube (42.0 cm effective length and 50 μm internal diameter) within 7 minutes under an applied voltage of 20 kV. Optimum separation and analyses were obtained using 25 mM borate buffer (pH 9.5) containing 5 mM β-cyclodextrin as the background electrolyte. The apparatus was equipped with a diode array detector (DAD) to identify lisuride at 240 nm and all other drugs at 200 nm. The addition of 5 mM β-cyclodextrin to the borate buffer has a significant effect on the separation of entacapone and benserazide in mixture I, and on the separation of selegiline and benserazide in mixture II, which cannot be achieved without it. The proposed method was successfully applied to analyse the studied drugs in their multi-component and single-component pharmaceutical dosage forms. The analytical results proved the linearity (r2 ≥ 0.9997), accuracy, precision (% RSD < 2), and selectivity of the proposed capillary electrophoretic method.

    Rod-shaped AgInTe2 nanocrystals (NCs) exhibiting intense near-band edge photoluminescence in the near-infrared (NIR) wavelength region, were successfully prepared by the thermal reaction of metal acetates and Te precursors in 1-dodecanethiol. Increasing the reaction temperature resulted in the formation of larger AgInTe2 NCs with crystal structures varying from hexagonal to tetragonal at reaction temperatures of 280 °C or higher. The energy gap was increased from 1.13 to 1.20 eV with a decrease in rod width from 8.3 to 5.6 nm, accompanied by a blue shift in the photoluminescence (PL) peak wavelength from 1097 to 1033 nm. The optimal PL quantum yield was approximately 18% for AgInTe2 NCs with rod widths of 5.6 nm. The applicability of AgInTe2 NCs as a NIR-emitting material for in vivo biological imaging was examined by injecting AgInTe2 NC-incorporated liposomes into the back of a C57BL/6 mouse, followed by in vivo photoluminescence imaging in the NIR region.

    DNA methylation is a stable epigenetic modification, which is well known to be involved in gene expression regulation. In general, however, analyzing DNA methylation requires rather time consuming processes (24–96 h) via DNA replication and protein modification. Here we demonstrate a methodology to analyze DNA methylation at a single DNA molecule level without any protein modifications by measuring the contracted length and relaxation time of DNA within a nanochannel. Our methodology is based on the fact that methylation makes DNA molecules stiffer, resulting in a longer contracted length and a longer relaxation time (a slower contraction rate). The present methodology offers a promising way to identify DNA methylation without any protein modification at a single DNA molecule level within 2 h.

    We report a highly-sensitive microchip electrophoretic method for the simultaneous analysis of gabapentin (GPN) and pregabalin (PGN). Analyses and separation of both compounds were achieved in a PMMA microchip after labelling with 4-Fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F). The separation of the labelled compounds was improved by addition of β-cyclodextrin (β-CD). Moreover, methylcellulose polymer was added to prevent analytes' adsorption on the microchannel walls. The sensitivity of the method was improved by stacking to quantify as low as 0.06 nM of each drug with detection limits of 12 pM.

    A field of recent diagnostics and therapeutics has been advanced with quantum dots (QDs). QDs have developed into new formats of biomolecular sensing to push the limits of detection in biology and medicine. QDs can be also utilized as bio-probes or labels for biological imaging of living cells and tissues. More recently, QDs has been demonstrated to construct a multifunctional nanoplatform, where the QDs serve not only as an imaging agent, but also a nanoscaffold for diagnostic and therapeutic modalities. This review highlights the promising applications of multi-functionalized QDs as advanced nanosensors for diagnosing cancer and as innovative fluorescence probes for in vitro or in vivo stem cell imaging in regenerative medicine.

    Cell collection based on deterministic lateral displacement (DLD) and cell circulation with a loop channel are two component technologies for stressless cell retention which have been developed with a view to working toward suspension culture in a microfluidic channel. DLD devices with low array angles collect floating S. cerevisiae through an array effectively. The DLD device with an array angle of 2.6°showed an efficiency of 91.7%. Two types of loop channels with a piezoelectrie pump make a stable two-phase laminar flow of a pre-filled fluid and supplied fluid. A loop channel with a connection between an inlet and outlet on the opposite side replaces a filled fluid in the channel with a supplied fluid, which is essential for supplying nutrient rich medium to cells in microfluidic channels as well as retaining cells in a microenvironment without external stresses.

    Separation and analysis of biomolecules represent crucial processes for biological and biomedical engineering development; however, separation resolution and speed for biomolecules analysis still require improvements. To achieve separation and analysis of biomolecules in a short time, the use of highly-ordered nanostructures fabricated by top-down or bottom-up approaches have been proposed. Here, we reported on the use of three-dimensional (3D) nanowire structures embedded in microchannels fabricated by a bottom-up approach for ultrafast separation of small biomolecules, such as DNA, protein, and RNA molecules. The 3D nanowire structures could analyze a mixture of DNA molecules (50-1000 bp) within 50 s, a mixture of protein molecules (20-340 kDa) within 5 s, and a mixture of RNA molecules (100-1000 bases) within 25 s. And, we could observe the electrophoretic mobility difference of biomolecules as a function of molecular size in the 3D nanowire structures. Since the present methodology allows users to control the pore size of sieving materials by varying the number of cycles for nanowire growth, the 3D nanowire structures have a good potential for use as alternatives for other sieving materials.

    Exploiting the nonequilibrium transport of macromolecules makes it possible to increase the separation speed without any loss of separation resolution. Here we report the arrangement of a nanostructure array in microchannels to control equilibrium and nonequilibrium transports of macromolecules. The direct observation and separation of macromolecules in the nanopillar array reported here are the first to reveal the nonequilibrium transport, which has a potential to overcome the intrinsic trade-off between the separation speed and resolution.

    Molecular filtration and purification play important roles for biomolecule analysis. However, it is still necessary to improve efficiency and reduce the filtration time. Here, we show self-assembled nanowire arrays as three-dimensional (3D) nanopores embedded in a microfluidic channel for ultrafast DNA filtration. The 3D nanopore structure was formed by a vapor-liquid-solid (VLS) nanowire growth technique, which allowed us to control pore size of the filtration material by varying the number of growth cycles. lambda DNA molecules (48.5 kbp) were filtrated from a mixture of T4 DNA (166 kbp) at the entrance of the 3D nanopore structure within 1 s under an applied electric field. Moreover, we observed single DNA molecule migration of T4 and lambda DNA molecules to clarify the filtration mechanism. The 3D nanopore structure has simplicity of fabrication, flexibility of pore size control and reusability for biomolecule filtration. Consequently it is an excellent material for biomolecular filtration.

    Since their discovery, carbon nanotubes have been prominent members of the nanomaterial family. Owing to their extraordinary physical, chemical, and mechanical properties, carbon nanotubes have been proven to be a useful tool in the field of plant science. They were frequently perceived to bring about valuable biotechnological and agricultural applications that still remain beyond experimental realization. An increasing number of studies have demonstrated the ability of carbon nanotubes to traverse different plant cell barriers. These studies, also, assessed the toxicity and environmental impacts of these nanomaterials. The knowledge provided by these studies is of practical and fundamental importance for diverse applications including intracellular labeling and imaging, genetic transformation, and for enhancing our knowledge of plant cell biology. Although different types of nanoparticles have been found to activate physiological processes in plants, carbon nanotubes received particular interest. Following addition to germination medium, carbon nanotubes enhanced root growth and elongation of some plants such as onion, cucumber and rye-grass. They, also, modulated the expression of some genes that are essential for cell division and plant development. In addition, multi-walled carbon nanotubes were evidenced to penetrate thick seed coats, stimulate germination, and to enhance growth of young tomato seedlings. Multi-walled carbon nanotubes can penetrate deeply into the root system and further distribute into the leaves and the fruits. In recent studies, carbon nanotubes were reported to be chemically entrapped into the structure of plant tracheary elements. This should activate studies in the fields of plant defense and wood engineering. Although, all of these effects on plant physiology and plant developmental biology have not been fully understood, the valuable findings promises more research activity in the near future toward complete scientific understanding of the behavior of carbon nanotubes in plants. This chapter focuses on the impact of carbon nanotubes on plants and the potential use of these unique nanomaterials in crop management and plant biotechnology.

    Formation behavior of lipid nanoparticles (LNPs) in microfluidic devices with a staggered herringbone micromixer (SHM) structure was investigated. The fundamental role for SHMs in LNP formation was demonstrated by determining such factors as the limiting SHM cycle numbers and the effect of flow rate. The SHM cycle numbers and the position of the first SHM were as significant as factors as the flow rate condition for producing the small-size LNPs.

    The importance of micro RNA analysis has been significantly increasing because the role of micro RNA in the human body has been gradually revealed. Despite its importance, the analysis has suffered from several troublesome pretreatments, which hamper any easy analysis. Therefore, an easy and high-throughput pretreatment method has been demanded. In this paper, we focused on the great advantages of microchip pretreatments over conventional manual pretreatments and developed a microchip for micro RNA extraction. To simplify microchip fabrication, we adopted poly(dimethyl siloxane) (PDMS) microchip and a silica membrane, which has rolls in RNA extraction fields. With silica membranes and the adhesion nature of PDMS, we could easily fabricate RNA extraction fields in the microchip. With this microchip, we successfully extracted micro RNA from cancer tumor cells. Though this is a preliminary experiment, and still has many improvement points, our device is expected to be applied for easy and fast micro RNA extraction from biological samples.

    Staphylococcal enterotoxins (SEs) have repeatedly caused food poisoning incidents worldwide. Some of the challenges associated with food poisoning outbreaks are that traditional detection methods are expensive and require long processing times and trained technicians. Microchannel devices represent a potential detection method by which these difficulties can be overcome. In this paper, we propose that immuno-pillar devices may represent a rapid, highly sensitive, and low-cost analytical system for the simultaneous detection of staphylococcal enterotoxin types A, B, and D (SEA, SEB, and SED) in milk. To prepare milk samples simulating food contaminated with SEs, commercial milk was spiked with equal amounts of SEA, SEB, and SED. A quantitative analysis of the milk samples was performed within 15 min by using the microchannel device. The analysis required only 0.5 μL of untreated milk sample. The resultant limit of detection was 15.6 pg mL-1 for each SE, and the total assay time and sensitivity were markedly shorter and higher, respectively, than those for commercially available assay kits. The detection range of each enterotoxin using these devices was estimated as 15.6 pg mL-1 to 100 ng mL-1, which completely covers the SE concentrations that can lead to foodborne diseases based on the U.S. Food and Drug Administration's criterion for the infectious SE dose in SE poisoning (1 μg SE). Using our devices, frequent assessment of food potentially contaminated with SE is possible.

    Molecular filtration and purification play important roles for biomolecule analysis. However, it is still necessary to improve efficiency and reduce the filtration time. Here, we show self-assembled nanowire arrays as three-dimensional (3D) nanopores embedded in a microfluidic channel for ultrafast DNA filtration. The 3D nanopore structure was formed by a vapor-liquid-solid (VLS) nanowire growth technique, which allowed us to control pore size of the filtration material by varying the number of growth cycles. λ DNA molecules (48.5 kbp) were filtrated from a mixture of T4 DNA (166 kbp) at the entrance of the 3D nanopore structure within 1 s under an applied electric field. Moreover, we observed single DNA molecule migration of T4 and λ DNA molecules to clarify the filtration mechanism. The 3D nanopore structure has simplicity of fabrication, flexibility of pore size control and reusability for biomolecule filtration. Consequently it is an excellent material for biomolecular filtration.

    We herein showed the analysis of exosomes derived from cancer cells by nanobiodevices. At fi rst, the nano-pore device formed by an electrode couple on a nano-pore was developed. The number and size of exosomes could be analyzed by measuring the current value of the tunnel current of exosomes in the culture supernatant poured into nano-pore device. Next, the nano-wire device formed by nano-wires on a microfl uidic device made from polymethylmethacrylate (PMMA) was developed. The exosomes could be collected from the culture supernatant with high effi ciency by using this nano-wire device, and then miRNA existing in the exosomes could be extracted by pouring the miRNA extraction liquid into the nanowire device. In addition, these devices were available to the analysis of exosomes in the serum and urine. Therefore, the analysis of exosomes derived from cancer cells by nanobiodevices may be useful for the diagnosis of cancers in early stage.

The principle of this method is based on intensity changes of diffracted light derived from the nanostructures. This method is very simple and useful for label-free detection of biomolecules, but further improvement in sensitivity was necessary to apply it to clinical applications. In this paper, we optimized optical system and device design to improve the sensitivity, and applied it to measure extracellular vesicles for cancer diagnosis. These results showed that our method had a potential to be a first screening method for cancer diagnosis.

    © 2014 AIP Publishing LLC. The effect of carbon nanowalls (CNWs) on the culturing rate and morphological control of cervical cancer cells (HeLa cells) was investigated. CNWs with different densities were grown using plasma-enhanced chemical vapor deposition and subjected to post-growth plasma treatment for modification of the surface terminations. Although the surface wettability of the CNWs was not significantly dependent on the CNWdensities, the cell culturing rates were significantly dependent. Morphological changes of the cells were not significantly dependent on the density of CNWs. These results indicate that plasma-induced surface morphology and chemical terminations enable nanobio applications using carbon nanomaterials.

    Recent reports suggest that rhinorrhea, defined as the presence of a runny nose unrelated to respiratory infections, allergies, or sinus problems, occurs more frequently among patients with Parkinson's disease (PD) than among healthy controls. We conducted a questionnaire survey in a multicenter study throughout Japan and compared the frequency of rhinorrhea between 231 PD and 187 normal control (NC) subjects. After excluding patients with rhinitis or paranasal sinusitis, a total of 159 PD and 59 NC subjects were included in our analysis. Rhinorrhea occurred more frequently in PD patients than NC subjects (33.3% vs. 11.9%; P = 0.01). Among PD patients, rhinorrhea was more common in men than women (P = 0.005). Rhinorrhea was not correlated with disease duration, modified Hoehn and Yahr score, disease type (akinesia rigidity vs. tremor dominant), or cardiac sympathetic function (evaluated by 123I- metaiodobenzylguanidine uptake). To our knowledge, this is the first multicenter study on the frequency of PD-related rhinorrhea in Asian countries. © 2014 Elsevier B.V.

    Over the past decade, considerable advances have been made in the discovery of gene targets in metabolic diseases. However, in vivo studies based on molecular biological technologies such as the generation of knockout mice and the construction of short hairpin RNA vectors require considerable effort and time, which is a major limitation for in vivo functional analysis. Here, we introduce a liver-specific nonviral small interfering RNA (siRNA) delivery system into rapid and efficient characterization of hepatic gene targets in metabolic disease mice. The comparative transcriptome analysis in liver between KKAy diabetic and normal control mice demonstrated that the expression of monoacylglycerol O-acyltransferase 1 (Mogat1), an enzyme involved in triglyceride synthesis and storage, was highly elevated during the disease progression. The upregulation of Mogat1 expression in liver was also found in other genetic (db/db) and diet-induced obese mice. The silencing of hepatic Mogat1 via a liver-specific siRNA delivery system resulted in a dramatic improvement in blood glucose levels and hepatic steatosis as well as overweight with no apparent overall toxicities, indicating that hepatic Mogat1 is a promising therapeutic target for metabolic diseases. The integrated approach with transcriptomics and nonviral siRNA delivery system provides a blueprint for rapid drug discovery and development.

    We reported an optical DNA/protein microfluidic sensor which consists of single stranded (ss) DNA-Cy3 probes on gold surface and simple line-shape microfluidic channel. These ssDNA-Cy3 probes with random sequence in bulk solution or on gold surface exhibits fluorescence enhancement after binding with complementary ssDNA (cssDNA) targets. Particularly it did not require complicated design or hairpin-like stem-loop conformation, which made it easier to be made and applied in analytes detection by fluorescence switching techniques. Using ssDNA-cy3 probes attached on gold surface in a microfluidic channel, strong fluorescence enhancement was measured by ssDNA with cssDNA binding or ssDNA with cssDNA-biotin binding. The following introduction of streptavidin resulted in fluorescence quenching (fluorescence decrease) because of the binding of hybridized DNA-biotin with streptavidin. This sensor showed strong affinity and high sensitivity toward the streptavidin, the minimum detectable concentration for streptavidin was 1. pM, equating to an absolute detection limit of 60. amol in this microfluidic channel. Microfluidic channel height and flow rate is optimized to increase surface reaction efficiency and fluorescence switching efficiency. In contrast to previously reported optical molecular beacon approach, this sensor can be used not only for the detection of cssDNA target, but also for the detection of streptavidin. This microfluidic sensor offers the promise of analyzing kinds of molecular targets or immunoreactions. © 2013 Elsevier B.V.

    At 14:46 local time on March 11, 2011, a magnitude 9.0 earthquake occurred off the coast of northeast Japan. This earthquake generated a tsunami that struck Japan as well as various locations around the Pacific Ocean. With the participation of about 300 researchers from throughout Japan, joint research groups conducted a tsunami survey along a 2,000 km stretch of the Japanese coast. More than 5,200 locations have been surveyed to date, generating the largest tsunami survey dataset in the world. The inundation height and run-up height were surveyed by laser, GPS, and other instruments, and the tidal correction has been accurately adjusted using a tidal database and a numerical simulation for Tohoku, an area where tide gauges were destroyed by the tsunami. Based on the survey dataset, the regional and local scale analyses were conducted to understand the basic characteristics of this event. Maximum run-up heights greater than 10 m are distributed along 500 km of coast in direct distance. The affected area of this event was several times larger than historically recorded in Tohoku. The mean inundation height in the southern Sanriku region is 1015 m and there are several peaks of inundation along the coast from the northern to middle part of Sanriku. © 2012 World Scientific Publishing Company and Japan Society of Civil Engineers.

    Stem cell transplantation has been expected to have various applications for regenerative medicine. However, in order to detect and trace the transplanted stem cells in the body, non-invasive and widely clinically available cell imaging technologies are required. In this paper, we focused on magnetic resonance (MR) imaging technology, and investigated whether the trimethylamino dextran-coated magnetic iron oxide nanoparticle -03 (TMADM-03), which was newly developed by our group, could be used for labeling adipose tissue-derived stem cells (ASCs) as a contrast agent. No cytotoxicity was observed in ASCs transduced with less than 100 μg-Fe/mL of TMADM-03 after a one hour transduction time. The transduction efficiency of TMADM-03 into ASCs was about four-fold more efficient than that of the alkali-treated dextrancoated magnetic iron oxide nanoparticle (ATDM), which is a major component of commercially available contrast agents such as ferucarbotran (Resovist), and the level of labeling was maintained for at least two weeks. In addition, the differentiation ability of ASCs labeled with TMADM-03 and their ability to produce cytokines such as hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF) and prostaglandin E2 (PGE2), were confirmed to be maintained. The ASCs labeled with TMADM-03 were transplanted into the left kidney capsule of a mouse. The labeled ASCs could be imaged with good contrast using a 1T MR imaging system. These data suggest that TMADM-03 can therefore be utilized as a contrast agent for the MR imaging of stem cells.

    Numerous nanobiodevices have been developed for cancer diagnosis through the analysis of cancer cells and cancer-related biomolecules, cancer gene therapy, and iPS cell-based regenerative medicine. A microchamber array, which is fabricated on a plastic chip, enables to develop a reliable circulating tumor cell (CTC) detection technique for cancer metastasis diagnosis. A nanopillar-array or a nanowire-array on a quartz chip allows ultrafast analysis of DNA and microRNA within 1 s for the molecular diagnosis of cancer. Immunopillar devices, which contain a tremendous amount of antibody-immobilized microparticles inside an immunopillar structure, have realized fast and low invasive &ldquo;from blood to analysis&rdquo; type biomarker detection of cancer with a pM detection sensitivity within 5 min. Quantum dots and gene delivery nanodevices are applied to single cancer cell diagnosis, <i>in vivo</i> imaging for iPS cell based regenerative medicine, and theranostic devices for cancer diagnosis and therapy.

    In this study, we herein examined the effects of the exosomes secreted from a stable hepatocellular carcinoma (HCC) cell line (HCC-exosomes) on the lumen formation of human umbilical vein endothelial cells(HUVECs). The uptake of HCC-exosomes by HUVECs and lumen formation by the HUVECs that included the exosomes were observed. The degree of lumen formation of HUVECs was dependent on the number of the HCC-exosomes. HCC-exosomes expressed a stress-induced heat shock protein associated with angiogenesis through the vascular endothelial growth factor(VEGF)receptor. In addition, the exosomes contained several microRNAs (miRNAs)reported to exist in the serum of HCC patients. The changes in the expression levels of miRNAs associated with angiogenesis were detected in the HUVECs treated with HCC-exosomes. Moreover, the abilities of the exosomes maintained after the treatment of cryopreservation. These results suggest that the HCC-exosomes play an important role in the angiogenesis. Further studies on the function of HCC-exosomes may provide a new target for HCC treatment.

    We report on fast biomolecules separation using three-dimensional nanowires structure devices. The three-dimensional nanowire structure can be synthesized and embedded in microchannel by Vapor-Liquid-Solid (VLS) technique. We decorate Au catalyst along the nanowires by DC sputtering and growth nanowire as a cycle to prepare the branch of the nanowire structure. This technique allows researchers to control the pore size of the three-dimensional nanowires by increasing the number of growth time. We separated small DNA molecules mixture (50-100 bp) within 35 seconds and proteins mixture (20-66 kDa) within 2.5 seconds under DC electric fields.

    We report a microfluidic molecular combing device to trap, stretch, and separate DNA at a singlemolecule resolution. In order to align long DNA into a single direction on surface, we demonstrated molecular combing by dewetting DNA solution inside a microfluidic channel. It used a surface tensional force at the air-water interface of DNA solution translating on a fabricated pattern (zigzag line). When the speed of molecular translation and adsorption were balanced by pressure control, DNA was stretched along the direction of flow. By specifying the location of DNA attachment at the zigzag vertices, the device served as a molecular ruler for sizing and sorting of single DNA molecules.

    Nanopore-based DNA sequencing is an emerging technology that may soon overcome even the current next-generation sequencing from the viewpoint of DNA sequencing cost and throughput. In this paper, we will show that recent advances of the "pretreatment" process using various nanostructures such as nanopillars, nanowires, and nanoslits structures inside microchannel. In addition, another type of micro and nanostructures such as micro and nanometer-scale chamber array on a chip becomes a powerful new tool for bioanalysis since it could stochastically capture and measure biomolecules at a single molecule level. The applications of these chamber array structures for single cell analysis will be also described.

We fabricated the nanopore channels which have 250 μm in length, 300 nm in width and 300 nm in depth for confinement of single DNA molecules, and measurement of single DNA molecules translocation velocities. Single DNA molecules translocation velocities in nanopore channels were controlled by fabricating the different nanostructures in front of nanopore channels, such as shallow channels and nanopillars. Based on these strategies, we successfully decreased the single DNA molecules translocation velocities to 7.7 ± 0.8×10<sup>-3</sup> cm/s in nanopore channels.

    We have developed a novel immunoassay device which has a long and thin wall structure inside a microchannel, hence the name 'immuno-wall device'. Unreacted antigens and antibodies were completely removed by just immersing the device in a washing buffer for 1 minute. The long structure also allowed us to analyze fluorescence intensity by using inexpensive desktop fluorescence reader ($6,000) instead of expensive fluorescence microscopes. By using the immuno-wall devices and the fluorescence reader, the high-sensitivity C-reactive protein assays were performed with sample-in-answer-out in 15 minutes.

The method achieves 3D fabrication without specific instruments or water-soluble support material. It provides the same level of minimum membrane thickness as a high end model commercial 3D printer, and the bond strength between the membranes have a sufficient pressure resistance to the flow of water with a syringe pump. Finally, two types of 3D microstructures were fabricated by the method: the 3D fractal structure called Menger sponge, and a channel within a channel structure for 3D sheath flow.

    <jats:p> Induced pluripotent stem (iPS) cells have received remarkable attention as the cell sources for clinical applications of regenerative medicine including stem cell therapy. Additionally, labeling technology is in high demand for tracing transplanted cells used in stem cell therapy. In this study, we used quantum dots (QDs), which have distinct fluorescence abilities in comparison with traditional probes, as the labeling materials and investigated whether iPS cells could be labeled with QDs with no cytotoxicity. iPS cells could not be labeled with QDs alone but required the use of cell-penetrating peptides such as octaarginine (R8). No significant cytotoxicity to iPS cells was confirmed by up to 8 nM QDs, and the iPS cells labeled with QDs maintained their undifferentiated state and pluripotency. These data suggest that QDs can be used for fluorescence labeling of iPS cells. </jats:p>

    Technologies for the transfection of antigen-encoding genes into the dendritic cells, and subsequent immune-activation are both prerequisites for a successful DNA vaccine. We herein report on the density-dependent enhancement of transgene expression by the simple modification by stearyl-conjugated KALA, an α-helical peptide (STR-KALA), onto a lipid envelope-type nanoparticle (the R8-MEND, an octaarginine-modified multifunctional envelope-type nano device). The enhanced transgene expression in the KALA-modified R8-MEND (R8/KALA-MEND) cannot be explained by cellular uptake and nuclear delivery efficacy. Thus, the post-nuclear delivery process (i.e. transcription), but not intracellular trafficking processes attributed the enhanced transfection efficacy. Microarray analyses revealed that transfection with the R8/KALA-MEND resulted in a greater perturbation in host genes expression in comparison with the R8-MEND and that this effect was time-dependent. Further pathway analyses in the category of transcription-related genes and a gene ontology analysis indicated that the R8/KALA-MEND stimulated the expression of transcription factors that are closely related to immune-activation (i.e. NF- kB and STAT). Inhibition of the transfection efficacy by blockage of the STAT pathways revealed that the enhanced transcription activity is the result of immune-stimulation. Collectively, the R8/KALA-MEND mounts a "switch-on" function that triggers signal transduction forward to the immune-stimulation analogous to an adjuvant, and consequently elicits active transcription. © 2013 Elsevier Ltd.

    We introduced a novel method for the rapid synthesis of silver nanohexagonal thin columns from an aqueous mixture of sodium thiosulfate (Na2S2O3) and silver chloride (AgCl) simply added to a phosphor bronze substrate. The reaction is based on galvanic displacement and the products are potentially useful for plasmonic applications. This journal is © the Owner Societies 2013.

    Denaturation is a first step for further treatment of DNA and is expected to be carried out rapidly on an integrated chip. A microheater is a promising device for the denaturation because of easiness for fabrication and operation. In the present study, we fabricated a microheater and thermometers on a coverslip and investigated response of temperature to application of voltage. In addition, our experiment and simulation proved local heating at an aimed area. Finally, we demonstrated denaturation of DNA in buffer solution, the result of which proved that the DNA around the heater denatured within 60 ms. © 2013 AIP Publishing LLC.
