Reversible electrochemical reduction and oxidation of cytochrome c at a bis(4-pyridyl) disulphide-modified gold electrode
Abstract
At a gold electrode on which bis(4-pyridyl) disulphide had been pre-adsorbed, horse heart ferricytochrome c exhibited a well developed quasi-reversible redox wave by cyclic voltammetry in the absence of any promoter in the solution.
