Green Synthesis of Silver Nanoparticles and Their Potential for Anti-bacterial Applications

Abstract

The eco-friendly production of silver nanoparticles (AgNPs) has become increasingly popular due to its sustainable, cost-efficient, and environmentally conscious approach in comparison to traditional chemical techniques. This method, which utilizes natural resources such as plant extracts, microorganisms, and enzymes, minimizes harmful chemicals, providing a safer alternative for AgNP synthesis. The process involves converting silver ions (Ag+) into nanoparticles, with biomolecules from plants or microbes serving as both reducing and stabilizing agents. This green synthesis reduces environmental risks and allows for the creation of AgNPs with specific sizes, shapes, and improved characteristics. Silver nanoparticles are well-known for their antimicrobial properties, which have been extensively researched for use in medicine, food packaging, and environmental management. Their minute size and expansive surface area enhance their interaction with microbial cell membranes, disrupting essential cellular functions. The distinct physicochemical properties of green-synthesized AgNPs, including their surface charge and stability, often result in superior antimicrobial effectiveness compared to their chemically synthesized counterparts.
