Abstract:
1. A microchip comprising a first layer and a second layer, said first layer comprising: at least one main separation channel formed in a channel forming medium, said main separation channel containing microfluids when in operation; electrodes in reservoirs at the ends of said main separation channel to drive electrophoretic separation; at least one detecting channel containing a first conductive element for performing electrochemical detection, said detecting channel being formed in said channel forming medium within said first layer and adjoining said main separation channel, wherein said main separation channel and said detecting channel intersect; and at least one reservoir containing a second conductive element for serving as a reference to said first conductive element, said reservoir being formed in said channel forming medium, said second layer being absent a conductive element, separation channel and detection channel.
