Bipolar electrodes (BPEs) have been used for decades in industrial applications ranging from organic electrosynthesis to catalysis. Recently, sensor platforms have been reported in which electrochemiluminescence (ECL) is used to readout the state of a bipolar sensor operating under steady state conditions. In these measurements ECL intensity is directly proportional to the analyte concentration. In contrast to these conventional amperometric sensors, the ECPA signal is based on a surface limited reaction, and therefore does not lend itself to such a straightforward readout strategy. In this paper, we describe the development of an ECPA based on a bipolar platform in which a square wave voltage program is employed both to interrogate and reset the redox state of the surface confined affinity complex. Signal averaging over multiple cycles allows us to detect proteins at low concentration levels.
