redox mediation

https://doi.org/10.1351/goldbook.09095
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.
Note: Electrocatalysis is accomplished by charge mediation but not all mediation results in electrocatalysis.
