| 摘 要： | 在以电化学方法证实了L－半胱氨酸对铜锌－超氧化物歧化酶在金丝电极上的电子传递过程起有效促进作用的基础上，应用共焦显微激光拉曼光谱测试技术对固体的L－半胱氨酸和铜锌－超氧化物歧化酶进行了测定和光谱分析，并对以电化学和浸渍两种不同方法修饰在金电极上的L－半胱氨酸，也作了相应的拉曼光谱测试研究。

| Abstract: | 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. |
