采用水相硅烷化方法，将3氨基丙基三甲氧基硅烷(APS)组装在湿化学法处理的单晶硅表面上.接触角、原子力显微镜(AFM)、X射线光电子能谱(XPS)表征结果显示得到了平整均匀的具有氨基表面的自组装膜.SEM观察表明，16nm的金纳米粒子可以在上述氨基表面上形成均匀的亚单层排布，得到具有Au纳米粒子/APS/Si形式的纳米复合结构，进一步的处理可以使金纳米粒子在表面上的排列由随机趋于有序化.

Chemically-wet treated silicon substrate was modified with self-assembled monolayer of 3-aminopropyl-trimethylsilane by aqueous phase silanization,giving an ultrasmooth and homogenous surface terminated with amino groups.Colloidal gold nanoparticles (15.7± 2.0 nm)were adsorbed on such a surface with a submonolayer coverage and a random particle distribution.Increases in local surface coverage and packing order were induced by capping the assembled gold nanoparticles with alkanthiol molecules in an enthanolic solution.
