Biosensor. (a) Testing chambers with patterned microelectrodes on Si substrate (6 reagent chambers incorporated into one platform); (b) brief schematic illustration of step-by-step immunochemical reaction on the electrode surfaces; (c) proposed detection system. The multichannel potentiostat is used to scan each reaction chamber on Biosensor.
