C 60 was covalently attached onto a self‐assembly monolayer (SAM) of glutathione (GSH) formed on a Au electrode. Characterization of the resulting monolayer was carried out on a FT‐IR spectrometer and its electrochemical properties were investigated with cyclic voltammetry and impedance methods. It was found that the pinholes on the C 60 ‐GSH monolayer showed the response of the opening and closing with the change of pH. The modified electrode can be used to determine NADH in neutral solution.
