| 摘 要： | 用原子力显微镜观察了谷胱甘肽-镉、铜配合物在硅片表面的形貌。低浓度时，谷胱甘肽-镉配合物主要以类球体颗粒无序地分散在基底表面，其表观高度和长度分别为(3.6±0.1) nm 和(60±10) nm 。随着浓度的增加，出现由小颗粒聚集而成的簇体。不同的缓冲溶液体系对谷胱甘肽-镉配合物的形貌无明显影响。谷胱甘肽-铜配合物首先由均匀的球体颗粒聚集成长链，然后岁链延伸方向的不同，形成类似于网状和线团状 2 种表面形貌，显示良好的方向性和均匀性。

| Abstract: | The surface morphology of the glutathione complex with cadmium and copper on silicon surface was studied by means of atomic force microscope (AFM).The results show that the glutathione-cadmium complex at a diluted concentration dispersed disorderly on the surface with spheroid or cylinder states. The apparent height of the spheroid is (3.6 ±0.1) nm and the width is (60 ±10) nm . The complex aggregated with the increase of its concentration, the dimmers and multimers aggregated from monomers formed clusters . The difference of AFM images of GSH-Cd complex on different buffer solution system is small. For GSH-Cu complex, firstly, some string bead chains were formed by aggregation of the uniform spheroid particles, then, under the influence of different directions, the long chains formed two kinds of different surface morphology orderly and uniformly. |
