A Recent Advancement Towards Herbal Biomass-Assisted Synthesis of Silver Nanoparticles

Abstract

Using plant extracts in metal nanoparticle production is a straightforward, practical, cost-effective, and ecologically benign alternative to the use of harmful chemicals. As a consequence, several approaches for the quick manufacture of silver nanoparticles that are acceptable to the environment and use aqueous extracts of plant materials including leaves, bark, and roots have been published recently. In this paper, recent advancements in the area of environmentally friendly manufacturing of silver nanoparticles (AgNPs) using diverse plant extracts are highlighted and expanded upon, along with the potential use of these materials as antibacterial agents. A thorough analysis of the potential effects of phytochemical concentrations in plant extracts, extraction temperatures, extraction solvents, reaction temperatures, reaction times, reaction pHs, and precursor concentrations. Furthermore provided are extensive details on the potential mechanism by which AgNPs have strong antibacterial action and induce cell death in pathogens by interacting with their cell walls. In addition, whereas chemical methods for shape-controlled synthesis are widely established, controlling the shape of biologically generated AgNPs has several advantageous effects on its activities.
