Methodology for miniaturized CE and insulation on a silicon substrate.
We have developed a synchronously switched cyclic capillary electrophoresis (CE) separator that is fabricated on a silicon substrate and glass. Au electrodes were also integrated on the chip that could be wire bonded to the printed circuit board (PCB). The advantage of using a cyclic separator is that it has the high resolution and the ability to separate each sample to the designated reservoir from mixed samples. This approach makes it possible to reduce the supplied voltage and the total chip size. Another goal of this work was to introduce the methodology of electroosmotic flow (EOF) on the silicon substrate and to separate DNA samples using a modified double-T injector.
