Antibacterial and Dye Degradation Activity of Green Synthesized Iron Nanoparticles

Abstract

Nanoparticles have a wide range of applications in various fields such as cosmetics, pharmaceuticals, and agrochemicals. Synthesis of nanoparticles using plant extract is a very efficient, cost‐effective, useful, and environmentally friendly method. A plant extract acts as a reducing agent in the formation of nanoparticles. Catharanthus roseus is one of the potential plants for biosynthesis of nanoparticles due to its easy availability. In the present study, the Catharanthus roseus plant extract was used to synthesize iron nanoparticles. UV‐vis spectroscopy, DLS, and FTIR were performed for characterization of synthesized nanoparticles. Further antibacterial and dye degrading properties of synthesized iron nanoparticles have been investigated. It was found that Catharanthus roseus ‐synthesized iron nanoparticles showed antibacterial activity against E. coli and dye degradation activity against methyl orange dye.
