摘要：

In author's laboratory,it has been demonstrated with electrochemical techniques that L-cysteine can be used as an effective electron transfer promoter to accelerate the electron transfer process of Cu/Zn superoxide dismutase on gold electrode. In order to reveal the mechanism of this promotion,confocal microscopic Raman spectroscopic technique is employed here to obtain Raman spectra of solid state SOD and L-cysteine modified gold electrode. Moreover,Raman spectra of L-cysteine modified gold electrode with two different approaches are also obtained. Analysis and discussion for these Raman spectra are reported.
