09095 IUPAC Gold Book - redox mediation 10.1351/goldbook.09095 09095 current 1 Detection principle for a chemically modified electrode (CME) in which an immobilized redox couple can shuttle electrons between the electrode and an analyte, for instance, one with difficult access to the electrode surface because of steric reasons. Electrocatalysis is accomplished by charge mediation but not all mediation results in electrocatalysis. PAC, 2020, 92, 641.
