The electrochemical behavior of superoxide dismutase (Cu, Zn SOD) was investigated on gold wire electrode and gold minigrid with thin layer cell by cyclic voltammetry. A quasi reversible redox wave of SOD has obtained on gold minigrid thin layer electrode, but only oxidation peak has observed on gold wire electrode. The electrochemical reaction parameters, such as the formal potential E 0 ′, diffusion coefficient D and standard rate constant k 0′ were estimated.
