| 中文摘要 | a new method for the fabrication of an integrated microelectrode for electrochemical detection (ecd) on an electrophoresis microchip is described. the pattern of the microelectrode was directly made on the surface of a microscope slide through an electroless deposition procedure. the surface of the slide was first selectively coated with a thin layer of sodium silicate through a micromolding in capillary technique provided by a poly(dimethylsiloxane) (pdms) microchannel; this left a rough patterned area for the anchoring of catalytic particles. a metal layer was deposited on the pattern guided by these catalytic particles and was used as the working electrode. factors influencing the fabrication procedure were discussed. the whole chip was built by reversibly sealing the slide to another pdms layer with electrophoresis microchannels at room temperature. this approach eliminates the need of clean room facilities and expensive apparatus such as for vacuum deposition or sputtering and makes it possible to produce patterned electrodes suitable for ecd on microchip under ordinary chemistry laboratory conditions. also once the micropattern is ready, it allows the researchers to rebuild the electrode in a short period of time when an electrode failure occurs. copper and gold microelectrodes were fabricated by this technique. glucose, dopamine, and catechol as model analytes were tested. |
