Biosynthesis, Spectroscopic Analysis, and Antibacterial Activity of Silver Nanoparticles

EasyChair Preprint no. 11142

Abstract

The biosynthesis of silver nanoparticles (AgNPs) through green and environmentally friendly methods has gained substantial interest in recent years due to its potential applications, including antibacterial activity. This abstract provides an overview of the biosynthesis of AgNPs, their spectroscopic analysis, and their antibacterial properties. Biosynthesis methods utilize natural sources, such as plant extracts, microorganisms, and other biological agents, to reduce silver ions into AgNPs. These methods are preferred over conventional chemical synthesis due to their sustainability and reduced environmental impact. In this review, we explore various biosynthesis routes and the factors influencing the synthesis process, including pH, temperature, and reactant concentrations. Spectroscopic analysis, including UV-Vis spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM), is crucial for characterizing the synthesized AgNPs. These techniques help determine the size, shape, crystallinity, and stability of the nanoparticles. Furthermore, the presence of functional groups from the biological agents used in biosynthesis can be identified through Fourier-transform infrared (FTIR) spectroscopy. The antibacterial activity of AgNPs is a significant focus of this review. AgNPs have been widely acknowledged for their potent bactericidal effects against various bacterial strains. Their antibacterial mechanisms involve disrupting the cell membrane, inducing oxidative stress, and interfering with cellular processes. Additionally, AgNPs have shown promising potential against antibiotic-resistant bacteria, making them valuable in the fight against drug-resistant infections.
