Review: Synthesis of Silver Nanoparticles in Several Methods

Abstract

One of the metal nanoparticles that is widely used is silver nanoparticles (AgNPs) because of their potential applications in various scientific fields. Silver is a material that is abundant in nature, attractive, and inexpenive. This paper aims to conduct a literature review from 12 papers on the synthesis of AgNPs from 2007 to 2020. Based on several articles, there are 3 methods for synthesizing AgNPs: physics, chemistry, and biology. Physical methods use laser ablation and arc-discharge, chemical methods use gamma irradiation and chemical reduction, and biological methods use bacteria, plants, and fungi. The best method is biosynthesis because it is facile, safe, cost-effective, and environmentally friendly. AgNPs produced from biosynthesis using plants is better than using bacteria and fungi because it produces pure and small particle of AgNPs.
