โœฆ Synopsis

An individually addressable microelectrode array system has bcen developed in the course ofthis work. The performance of this system was investigated using conventional electrochemistry (oxidation]reduction or ferrocene carboxylic acid) to demonstrate that independent potential control and current measurement at each of the array components was possible. The practical utility of this system has been demonstrated using a conducting polymer based microarray detection system subsequent to Ion Chromatography. The detection of simple electroinactive ions (e.g., CI-, SOa '--, K' , NH4 +) using the array system was achieved and the response at each ofthe array components was studied as a function of polymer composition.

In this article, we have demonstrated the feasibility of using dye binding interactions for the amperometric detection of proteins at conducting polymer coated electrodes with flow injection analysis. Incorporation of appropriate dyes into the conducting polymer during synthesis enables sensitive an
