摘要： 采用光化学还原方法合成人免疫球蛋白(IgG)包裹的银纳米颗粒胶体溶液,用X射线衍射仪(XRD)和透射电子显微镜(TEM)等技术对合成的IgG包裹的银纳米颗粒组分和形态进行表征。结果表明,采用光化学还原方法合成IgG包裹的银纳米颗粒,粒径在10 nm左右。得到的胶体溶液为黄色混浊液体,通过白光观察时,该胶体溶液呈透明状,其颜色随着制备条件的不同而发生变化。本文对产生这种特殊光学透光现象的原因进行了初步分析。

关键词: 银纳米颗粒, 人免疫球蛋白, 光化学还原

Abstract: IgG-encapsulated Ag nanoparticles were obtained by asimple photoreduction method.The prepared samples were characterized by TEM and XRD.The resultsshowed that Ag nanoparticles with diameters about 20 nm were fabricated withinIgG.The solutions obtained are opaque and yellow-brown in colors,but became transparent and exhibited different colors when viewed through white light.A tentative mechanism was proposed for the formation of the special optical phenomenon.

Key words: Ag nanoparticles, IgG, photoreduction
