摘　　要：虽然对于纳米金颗粒(AuNPs)和细胞相互作用的研究有着大量的报道,但是其结果常常是互相矛盾的。对其机理的研究更是十分的贫乏。这些研究中的一个核心问题,即AuNPs对生物体或细胞是有毒的还是有利于其生长的。虽然AuNPs在生物体内的作用远比体外的简单细胞反应要复杂得多,涉及到与生物体中多种组分的作用,从而引起极为不同的免疫反应、代谢机理等。但是在体外进行纳米颗粒的毒性和促进细胞生长相互作用的微观研究仍将为AuNPs在体内的作用提供十分重要的理论依据。本综述主要从AuNPs尺寸、表面电荷、颗粒聚集状态等方面介绍近年来关于AuNPs的细胞毒性和促细胞生长的体外研究结果,并对其作用机理进行初步的探讨。The cytotoxicity of gold nanoparticles（AuNPs） and the effects on cell growth have been reported trememdously, however the experiment results are often contradicted. The studies on the underlying mechanism are even rarely reported. A core problem in these researches is whether the AuNPs are toxic or benefit to the cell growth. It is understandable that the reactions of AuNPs in human body is much more complicated than those observed in vitro. Multiple components are involved in the human body, causing different immune responses and metabolism outputs. Nevertheless, microscopic investigation outside the human body still is a very important method to provide evidences for the mechanism of the role of AuNPs playing in the body. This review mainly introduces the results of the cytotoxicity of AuNPs and the effects on cell growth in vitro in terms of the size, surface charge and component, and the aggregation of AuNPs. The possible machanism involving in the nanoparticle effect has been discussed.
