Abstract

Implementing a reliable reference electrode in miniaturized electrochemical sensors is challenging. Here, we present an alternative approach, based on redox cycling within a nanogap sensor consisting of two parallel electrodes, in which the reference electrode is omitted altogether. We show that on disconnection of the reference electrode, the solution potential floats to a certain value, which is explored theoretically and experimentally in order to quantitatively predict the potential. The obtained results are in good agreement with the theoretically reconstituted results.
