纳米金粒子的生物组装技术与光学检测技术研究

The Study of Bioassembly of Nanogold and Optical Detection

生物大分子包被纳米金粒子形成纳米金探针 ,通过生物亲和反应可以联接纳米金探针 ,构成纳米金粒子的复合结构。采用透射电镜和光谱分析来表征这一复合结构 。

Nanogold probe, with nanocrystal core and overlapped macromolecular, was assembled by bioaffinity reaction. Transmission Electron Microscope and optical spectrum was used as characterization method of nanogold bioassembly. The optical method was applied in immunosensing.
