Title:
METHOD FOR PREPARING SIZE-ADJUSTABLE GOLD NANOPARTICLES
Document Type and Number:
WIPO Patent Application WO/2022/016741
Kind Code:
A1
Abstract:
Disclosed are a method for preparing size-adjustable gold nanoparticles, the method comprising the following steps: S1. formulating an aqueous mixed solution of glycerol, ascorbic acid, sodium citrate and polyvinylpyrrolidone as a solute; and S2. adding an aqueous chloroauric acid solution to the aqueous mixed solution and reacting same while stirring to obtain gold nanoparticles, wherein the concentrations of the components in the reaction solution are: 5-80 v% of glycerol, 1-10 wt% of ascorbic acid, 0.05-0.5 wt% of sodium citrate, 0.05-0.5 wt% of polyvinylpyrrolidone, and 0.01-0.1 wt% of chloroauric acid. The method for preparing size-adjustable gold nanoparticles of the present invention has simple steps, and can be carried out at a normal temperature and a normal pressure without a complicated device. The gold nanoparticles thus synthesized are size-controllable.
