Capillary electrophoresis chip with integrated electrodes

In order to realize total reaction and analysis systems, we have been developing PDMS (polydimethylsiloxane) based microbiochemical systems. Several components, such as microreactors, a small volume liquid handling chip, and capillary gel electrophoresis chips, are fabricated through molding processes against negative masters fabricated with SU-8 photoresist on silicon wafers. This year we have concentrated on the integration of the temperature control devices on a glass substrate that forms a hybrid structure bonded with the PDMS microchip. The integrated chip could be used for continuous-flow PCR, which is one of the indispensable reactions for the in-situ gene analysis. The detailed designs, fabrication processes, and chemistries will be discussed in the presentation.
