摘　　要：制备了 3-巯基丙酸包裹的金钠米粒子水溶胶。在胺丙基三甲氧基硅烷覆盖的 Si或Si O2 基底上组装了上述金纳米粒子的单层膜和由 1 ,6-二巯基己烷联接的金纳米粒子多层膜。紫外 -可见吸收光谱和Aqueous gold colloid capped by 3 mercaptopropionic acid has been prepared. Gold nanoparticle monolayer and multilayer cross linked by 1,6 hexamedithiol were bound to (3 aminopropyl) trimethoxysilane coating on Si or SiO 2substrates. The lamellar periodic structure of gold particle multilayers was identified by UV Vis spectroscopy and X ray diffraction.
