Green synthesis of Silver Nanoparticles and their antimicrobial applications

Abstract

The exceptional antibacterial properties of silver nanoparticles (Ag NPs) and their prospective uses in different fields have attracted a lot of interest in contemporary times. The chemical agents used in the preparation of Ag NPs are hazardous to human health and the environment. In contrast to chemical approaches, green synthesis techniques involve the use of natural resources, which accomplish the principles of green chemistry and sustainable development goals (SDGs). In this regard, this review article delves into a comprehensive analysis of the green synthesis methods employed for the production of Ag NPs and their utilization as diverse antimicrobial agents. In addition to exploring the many antimicrobial uses of Ag NPs production, this article attempts to give a thorough examination of the processes behind the antibacterial activity of Ag NPs. This review provides in-depth mechanisms of antimicrobial action, including rupture of membranes, production of reactive oxygen species (ROS), and disruption of cellular functions. Thus, this article explores recent insights into green synthesis approaches for the preparation of Ag NPs which are effectively utilized as antimicrobial agents.
