Avidin was modified on indium tin oxide (ITO) electrode surfaces through charge interaction. Then graphene oxide (GO) sheets were deposited on the avidin-modified ITO surfaces, which was followed by an electrochemical reduction of GO for preparing electrochemically reduced graphene oxide (ERGO)-modified ITO surfaces. After an immobilization of biotinylated probe biomolecules on the avidin binding sites, the resulting surfaces were employed as sensing platforms for electrochemical detection of target molecules. For enhancing the performance of the sensor, an electrocatalytic activity of ERGO toward redox active molecules such as benzoquinone was employed in electrochemical measurements. In this contribution, we present an optimization procedure of the sensor platform for the sensitive detection, and demonstrate a high efficiency of the platform.
