Abstract

A comprehensive analysis of an aqueous solution of gold nanoparticles with an average size of 6 nm in a citrate buffer has been carried out, with investigation of the solution rheology and structure by electron and atomic force microscopy. A deviation of the rheological behavior of hydrosol from the Newtonian properties is found even at low gold nanoparticle concentrations. The specific features of the rheological behavior of hydrosol are explained based on the transmission electron microscopy (TEM) data.

稳定化金纳米粒子水溶胶的微观结构和流变行为

摘要

对平均尺寸为 6 nm 的金纳米粒子在柠檬酸盐缓冲液中的水溶液进行了综合分析，并通过电子和原子力显微镜研究了溶液的流变学和结构。即使在低金纳米颗粒浓度下，也发现水溶胶的流变行为与牛顿特性的偏差。基于透射电子显微镜 (TEM) 数据解释了水溶胶流变行为的具体特征。
