Abstract

Microchip electrophoresis technique have been developed fully these years, especially the detection methods have been the research focuses. With the help of MEMS technique, the system integrating function are more and more. This paper presented a novel design and fabrication method about this electrophoresis chip with the detection electrodes. The two-layer structure, one is PDMS substrate to fabricate the electrophoresis microchannel, the other is the glass substrate with the Pt electrodes, are bonded together. The soft lithography with the two molds is developed to accommodate the PDMS curing and peeling off. Then the inorganic cation Cu²⁺ is introduced and tested the project feasibility. All these works are laid a stable foundation for the chip appliance.
