Abstract

We report the reuse of indium tin oxide (ITO) electrode surfaces in electrochemical applications via anodic desorption of the organic layer that was prepared by the anodic deposition of a diamine, 2,2′-(ethylenedioxy)bis(ethylamine) onto the ITO surfaces. The layer was desorbed by applying anodic potential pulses that alternated between 0 and 2.2V. The desorption strategy permitted the ITO surfaces to be regenerated multiple times. We demonstrated that the reused surfaces could be successfully used for the preparation of an electrochemical sensor platform involving electrochemically reduced graphene oxide. The platform was applied to the electrochemical determination of uric acid in the presence of excess ascorbic acid.
