CHARACTERIZATION AND ANTIBACTERIAL EFFICACY OF ALBIZIA AMARA MEDIATED BIOGENIC SILVER NANOPARTICLES

Green Nanotechnology techniques have emerged in response to the growing need for sustainable and eco-friendly approaches to synthesize nanoparticles. The present study provides an endurable procedure for the green-mediated synthesis of silver nanoparticles (AgNPs) from Albizia amara leaf extract and its antibacterial potential. Various techniques like UV-Vis spectroscopy, FT-IR, XRD and FE-SEM were employed to characterize the properties of the silver nanoparticles. The UV-Vis spectra exhibited a maximum peak for AgNPs at 425nm, confirming their absorption capability. The presence of OH and COOH functional groups was evident from the FT-IR analysis which contributes to the stability of nanoparticles. The XRD patterns displayed distinct diffraction peaks. The morphology of AgNPs was determined by FE-SEM and the elemental composition of synthesized nanoparticles was exhibited in EDS mapping. When the silver nanoparticle was tested against the clinical pathogens, the results demonstrated a considerable inhibition of bacterial growth. The magnitude of the zone of inhibition exhibited by silver nanoparticles showed high antibacterial activity with zones measuring 19mm against Enterococcus faecalis strain. The results state that the synthesized nanoparticle may be a potent growth inhibitor against the pathogenic strains
