Document Type and Number:
WIPO Patent Application WO/2023/070967
Kind Code:
A1
Abstract:
A method for preparing silver nanoparticles on the basis of Amaranthus tricolor L extract. An Amaranthus tricolor L ethanol extract is mixed with a silver ion solution, which react to generate silver nanoparticles. The Amaranthus tricolor L extract is used for reducing silver ions, and silver nanoparticles having a particle size of 1-30 nm can be prepared. Amaranthus tricolor L extract is used to prepare silver nanoparticles, the preparation method is simple and easy to implement, operability is high and costs are low. The Amaranthus tricolor L extract serves as a reducing agent and a stabilizer at the same time, no other chemical components need to be added in the reaction process, and a large number of silver nanoparticles are prepared in a short space of time. The present invention is a simple and also environmentally friendly silver nanoparticle preparation method, and the prepared and obtained silver nanoparticle solution has an efficient antibacterial effect.
