摘要 研究了四种D-氨基葡萄糖甘氨酸混配金属配合物的表面增强喇曼光谱(SERS),发现它们在银胶上的吸附方式基本相同,因而SERS光谱也基本相似,并用SERS光谱研究了它们与DNA的相互作用,发现这四种化合物与DNA的作用能力有很大不同,Co(Ⅲ)GluG是值得进一步研究的可能抗癌药物。 Raman scattering of four complexes derived from d glucosamine and α glycine and their effects on DNA were studied with surface enhanced Raman spectra (SERS).It was found that their SERS had shown little difference for their similar structural.Their interaction abilities on DNA were poor according to the change of their SERS spectrun after adding DNA to their water solution except for Co(Ⅲ)GluG,which has strong effect on DNA.NiGluG′s adsorptive ability on Ag sol is the strongest among other three complexes.
