"Towards the development of multianalyte electrochemical immunoassays three individually addressable micro-electrode array (MEA) type working electrodes and a reference electrode were integrated into a 4 mu L volume, planar electrochemical cell. To model the simultaneous determination of multiple antigens in the cell with enzyme linked immunosorbent assays (ELISAs) glucose oxidase (GOx), alkaline phosphatase (ALP), and beta-galactosidase (beta-GAL) were immobilized site specifically onto the individual MEA surfaces and the biocatalitic activity of these surface confined enzymes were evaluated by measuring the products of the enzyme catalyzed reactions directly on the gold ...
