Plant-based green synthesis of silver nanoparticle via chemical bonding analysis

Abstract

Nanotechnology that involves the biological synthesis of nanoparticles is a relatively recent subject with advantages over chemical and physical synthesis procedures with respect to the economics and the environment. This study is the first to use the brown sea algae Sargassum muticum (S. muticum) as a reducing agent to generate nanostructured silver particles (AgNP). Using FTIR, XRD, and UV–vis spectroscopy, the structure, shape, and optical features of the synthesized nanoparticles have been exhaustively characterized. Using a UV–visible spectrophotometer, a clear absorption peak at 390 nm demonstrated the synthesis of AgNP. By crystallizing chemicals, nanoparticles were formed. The XRD pattern validated the results.
