20080241417 | PROCESS FOR MANUFACTURING A FLEXIBLE SUPPORT FOR AN ELECTROPHORETIC MEDIUM - A process for making a support for an electrophoretic medium comprising the steps of: applying an agarose coating to a corona treated polymeric film by transferring a layer of agarose solution onto a surface of the corona treated polymeric film. The pH of the agarose solution can be generally maintained between about 8 and about 11 and the concentration of the agarose solution can be generally maintained between about 0.1 and about 0.4% agarose by weight. The agarose powder used to make the agarose solution can be pre-treated by introducing a fresh reducing atmosphere above the agarose powder and exposing the agarose powder to a reducing atmosphere. The reducing atmosphere treatment may be repeated at least three times. | 10-02-2008 |
20090117287 | MODIFICATION METHOD OF MICROCHANNELS OF PDMS MICROCHIP USING SOL-GEL SOLUTION - The present invention provides a method for modification of microchannels of a polydimethylsiloxane (PDMS) microchip, which includes the steps of: a) mixing an alkoxysilane precursor, an alkyl alkoxysilane precursor, and a solvent to prepare a sol-gel solution; b) oxidizing microchannels of the PDMS microchip; and c) coating the oxidized microchannels with the sol-gel solution prepared in step a). The PDMS microchip modified according to the method of the present invention shows higher hydrophilicity than an unmodified PDMS microchip. And, when the modified PDMS channels are filled with an organic solvent, channel swelling can be reduced, and thus various organic solvents can be used for the modified PDMS microchip compared to an unmodified PDMS microchip. Further, it can be widely applied for various fields because absorptivity of non-polar substances can be reduced. | 05-07-2009 |
