利用银镜反应原理，使用葡萄糖作为还原剂还原氯金酸，在表面活性剂存在条件下制备单分散Au纳米粒子。使用紫外-可见光谱研究在反应体系中添加表面活性剂对于所制备产物的形貌尺寸，稳定性产生的影响。结果表明：阴离子及非离子表面活性剂的添加有利于减缓银镜反应速度，阴离子型表面活性剂体系可获得尺寸为15 nm A u纳米粒子，并呈现一定的分散性；在非离子型表面活性剂体系中可获得5～10 nm球形A u纳米粒子，分散性较好。

Monodisperse Au nanoparticles are prepared by applying the principle of silver mirror reac-tion and using glucose as the reducing agent under the condition with the surfactant .The effects of adding the surfactant in the reaction system on morphology ,size and stability of the product prepared are studied with UV-visible spectrum .The results show that the addition of anionic and nonionic surfactants contribu-ted to showing dow n silver mirror reaction ;anionic surfactant system can gain 15 nm Au nanoparticle with certain dispersibility ;nonionic surfactant system can gain 5~10 nm spherical Au nanoparticles with good dispersibility .
