7 pagesDate: November 2, 2023


Nanotechnology has emerged as a pivotal field in the quest for innovative solutions to combat microbial infections and explore the synthesis of nanoparticles through sustainable, eco-friendly methods. This study delves into the biosynthesis of silver nanoparticles (AgNPs) through an innovative biological route using plant extracts, aiming to unveil their spectroscopic fingerprints and antibacterial efficacy. Biogenic synthesis of AgNPs was achieved using an aqueous extract of a specific plant species. The formation of AgNPs was confirmed by UV-visible spectroscopy, which displayed characteristic absorption peaks in the range of 400-450 nm. Fourier-transform infrared (FTIR) spectroscopy analysis was conducted to elucidate the biomolecules responsible for the reduction and stabilization of AgNPs.The morphology and size of the synthesized AgNPs were investigated using transmission electron microscopy (TEM), revealing spherical nanoparticles with an average size of approximately 20-30 nm. X-ray diffraction (XRD) analysis was employed to determine the crystalline structure of the nanoparticles, which predominantly exhibited a face-centered cubic (FCC) structure. This study unveils the intriguing biosynthesis of silver nanoparticles using plant extracts and provides a comprehensive characterization of their spectroscopic properties. The biosynthesis of AgNPs, coupled with their exceptional properties, represents a promising avenue in the ongoing journey toward sustainable and effective antimicrobial solutions.
