FOCUSING ON THE RECENT PROGRESS IN ANTIMICROBIAL POTENTIALS OF PLANT EXTRACTS-MEDIATED SYNTHESIZED SILVER NANOPARTICLES

Using plant extracts to synthesize metal nanoparticles is one of the easiest, most convenient, cost-effective, and ecologically acceptable ways of avoiding hazardous chemicals. As a result, many environmentally acceptable methods for the fast production of silver nanoparticles utilizing aqueous extracts of plant components such as leaves, bark, and roots have been described in recent years. This study highlights and expands on recent discoveries in the green production of silver nanoparticles (AgNPs) utilizing various plant extracts and their prospective uses as antimicrobial agents. A systematic in-depth discussion on the possible influence of phytochemicals and their concentrations in plant extracts, extraction solvent, and extraction temperature, as well as reaction temperature, pH, reaction time, and precursor concentration. Extensive details of the probable mechanism of AgNPs’ interaction with microbe cell walls, which leads to cell death and strong antibacterial activity, have also been developed. Furthermore, even though chemical techniques for shape-controlled synthesis are well-known, regulating the shape of biosynthesized AgNPs has numerous beneficial impacts on its activities.
