Abstract
We developed a permanent surface coating method which integrates the advantages of poly(dimethylsiloxane) (PDMS) and glass as microchip materials. This method is based on the sol-gel process between PDMS surface and sol-gel solution containing the alkoxysilanes as a precursor and is able to create the silica coated PDMS. The most important point is the possibility of the local silica coating through corona discharge in only defined region of microchannel networks. Silica coated PDMS surface is uniform, hydrophilic and resistant to organic solvent. These improved properties provide the broaden applications as microfluidic devices.
