合成不同粒径大小的金纳米粒子的分析研究

摘要

As one of the most important metal nanoparticles, gold nanoparticles have been widely used in many fields such as biosensing, catalysis, drug carrier and gene chip due to their unique catalytic, opti-cal and electrical properties. Gold nanoparticles in various applications to control its specific shape, size, spatial structure is of great significance but faces some synthetic challenges.Therefore,in this paper,differ-ent synthesis methods were used to synthesize gold nanoparticles with different particle sizes, and gold nanoparticles of different particle sizes were successfully synthesized.%金属纳米粒子中金纳米粒子作为其中最重要的一员,由于其具有独特的催化性能、光学性能、导电性能,使其在生物传感[1]、催化、药物载体、基因芯片[2]等众多领域有着广泛的应用.纳米金在各个应用中控制其特定形貌、尺寸大小、空间结构具有十分重要的意义,但又面临一定的合成挑战.本文针对合成不同粒径的纳米金采用了不同的合成方法,成功地合成出不同粒径大小的纳米金.
