JOURNAL OF CHROMATOGRAPHY A Vol. 1043 ( 1 ) page： 19 - 25 2004.7

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE BV

In proteomics, pre-treatment of sample is the most important procedure to remove the matrix for interfacing with mass spectrometry (XIS). Additionally, for the samples with low concentration, the process of pre-concentration is required before MS analysis. We have newly developed solid-phase extraction (SPE) tool with pipette-tip shape for purification of bio-samples of various characteristics, utilizing monolithic silica gel as medium. The monolithic silica surface was modified with a C-18 phase or coated with titania phase. A C-18-bonded tip and a non-modified tip were used for sample concentration, desaltination and removal of detergents from sample. A titania-coated tip was also applied for purification and concentration of phosphorylated peptides. This novel pre-treatment method using monolithic silica extraction tip is much effective and suitable for protein analysis. (C) 2004 Elsevier B.V. All rights reserved.

CONTINUOUS NANOPHASE AND NANOSTRUCTURED MATERIALS Vol. 788 page： 353 - 358 2004

Language：English Publishing type：Research paper (scientific journal) Publisher：MATERIALS RESEARCH SOCIETY

Formation of hierarchical macropores and mesopores in ethylene-bridged polysilsesquioxane sol-gel systems via concurrent sol-gel transition and phase separation induced by the incorporation of supramolecular templats has been investigated. A series of poly(ethyleneglycol)-poly(propyleneglycol)- poly(ethyleneglycol) triblock copolymers, EOPOEOs, have been employed as supramolecular templates, while 1,2-bis(trimethoxysilyl)ethane was used as a polysilsesquioxane source. Successful combination of templated mesopores and well-defined macropores due to phase-separation has been found in the system with EOPOEOs having 70 PO units and respective 20 EO units. Although similar macroporous morphology has been obtained for all the EOPOEOs with EO chain longer or shorter than 20 units, the optimum composition for the co-continuous macropores and that for templated mesopores deviated from each other, resulting in the failure of producing hierarchical macropores and mesopores.

BIOMATERIALS Vol. 24 ( 10 ) page： 1729 - 1735 2003.5

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCI LTD

An ethylene-vinyl alcohol copolymer (EVOH) was treated with a silane coupling agent and calcium silicate solutions, and then soaked in a simulated body fluid (SBF) with ion concentrations approximately equal to those of human blood plasma. A smooth and uniform bonelike apatite layer was successfully formed on both the EVOH plate and the EVOH-knitted fibers in SBF within 2 days. Part of the structure of the resulting apatite-EVOH fiber composite was similar to that of natural bone. If this kind of composite can be fabricated into a three-dimensional structure similar to natural bone, the resultant composite is expected to exhibit both mechanical properties analogous to those of natural bone and bone-bonding ability. Hence, it has great potential as a bone substitute. (C) 2003 Elsevier Science Ltd. All rights reserved.
