Are there any suitable redox active cations that can be used instead of the ferricyanide/ferrocyanide redox couple for electrochemical biosensors?

Some label free electrochemical biosensors based on affinity events between immobilized antibodies and proteins use the ferricyanide/ferrocyanide redox couple as a redox active probe. These...
