Synthesis and Characterization of Silver Nanoparticles Using Elaeocarpus ganitrus Leaf Extracts; A Sustainable Approach with Antimicrobial Activity

Abstract

The current study reports the production of silver nanoparticles (AgNPs) with aqueous leaf extracts from Elaeocarpus ganitrus (Rudraksha). The synthesized NPs were characterized using FTIR, UV-vis spectroscopy, SEM, and XRD. The synthesis of AgNPs was proven by a characteristic peak in the UV-Vis spectra at 432 nm. Functional groups like hydroxyl and carbonyl were found via FTIR analysis. XRD examination confirmed the crystal structure and found their size to be 11.93 nm. XRD showed the crystalline NPs with diffraction patterns matched the face-centred cubic structure of silver. The SEM image exhibited primarily spherical, uniformly sized NPs with some aggregation. The effectiveness of the AgNPs against specific types of bacteria was determined using the agar-well diffusion method. These results highlight the potential of Rudraksha-mediated silver nanoparticles as potent antibacterial agents that are safe for application in biomedical and eco-friendly settings.
