Rapid Green Synthesis of Silver Nanoparticles (AgNPs) Using (Prunus persica) Plants extract: Exploring its Antimicrobial and Catalytic Activities

Abstract

Fabrication of nanoparticles by using Green synthesis is done because of its wide applications in different field such as biomedical, agriculture and food engineering. In this paper plant extract is used that contain alkaloids, flavonoids, saponins, steroid compounds, acts as reducing and stabilizing agents. The presence of AgNPs in solution was identified by UV-visible spectrophotometer. The size of AgNPs was in the range of 40-98 nm determined by Zetasizer. Spherical Shape and crystalline nature of AgNPs was confirmed by FESEM and XRD. Process Optimization was done by varying leaf extract volume, silver nitrate concentrations, pH, temperature, and time of reaction. The biosynthesized AgNPs exhibited antibacterial and catalytic activity against bacterial strains E. coli and V. cholera, and heavy metal such as Cadmium (Cd) and Palladium (Pd) in varying extents. Biosynthesized AgNPs were found to have a higher inhibitory action against E. coli and removal efficiency of Cd is higher than Pd.
