The electrochemical characteristics of C-60-glutathione modified Au electrode and the electrocatalytic oxidation of NADH

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