Optimization of zeta potential distributions for minimal dispersion in an electroosmotic microchannel
Optimization of the zeta potential distributions at the walls for minimal dispersion in an electroosmotic microchannel is performed based oil the variational approach. Ill the present problem, the governing equations are the steady flow equations and the unsteady mass transport equation. Based oil the calculus of variations and the method of Lagran...
Integrated light collimating system for extended optical-path-length absorbance detection in microchip-based capillary e...
We have developed an integrated light collimating system with a microlens and a pair of slits for extended optical path length absorbance detection in a capillary electrophoresis (CE) microchip. The collimating system is made of the same material as the chip, poly(dimethylsiloxane) (PDMS), and it is integrated into the chip during the molding of th...

Preparation of superparamagnetic immunomicrospheres and application for antibody purification / J. Appl. Polym. Sci.
A novel and effective protocol for the preparation of superparamagnetic immunomicrospheres has been developed. First, micro-size magnetic poly (methacrylate-divinylbenzene) (PMA-DVB) spheres were prepared by a modified suspension polymerization method. The oleic acid coated magnetite (Fe3O4,) nanoparticles made by coprecipitation were mixed with mo...
A dielectric biosensor using the capacitance change with AC frequency integrated on glass substrates
Glass-based microchannel chips were fabricated using photolithographic technology, and Pt thin-film microelectrodes as dielectric biosensors were integrated on them. From capacitance-frequency measurements at various interelectrode distances and ionic concentrations, a significant difference between deionized (DI) water and tris-ethylenediaminetetr...
Surface modification of poly(dimethylsiloxane) microchannels
This review looks at the efforts that are being made to modify the surface of poly(dimethylsiloxane) (PDMS) microchannels, in order to enhance applicability in the field of microfluidics. Many surface modifications of PDMS have been performed for electrophoretic separations, but new modifications are being done for emerging applications such as het...
Affinity extraction of BSA with reversed micellar system composed of unbound Cibacron Blue / Biotechnol. Prog.
Affinity Cibacron Blue 3GA (CB) dye in aqueous phase was directly transferred to the reversed micelles due to electrostatic interaction between anionic CB and cationic cetyltrimethylammonium bromide (CTAB). The bovine serum albumin (BSA) transfer to the reverse micelles increases significantly in a wide range of pH by the addition of a small amount...
