Abstract

This study investigates the green synthesis and antibacterial potential of silver nanoparticles (AgNPs) derived from Calotropis procera leaf extract. The AgNPs was characterized using Ultraviolet-Visible (UV-VIS) Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), Scanning and Transmission Electron Microscopy (SEM and TEM), Energy Dispersive X-ray (EDX) and X-ray Diffraction (XRD). The spectrum from UV-VIS had a peak centered at 445 nm confirming the formation of AgNPs, SEM-TEM micrographs showed them as aggregated, spherical in shape and about 15.30 – 17.66 nm in size, while EDX revealed Ag with highest proportion (75.56 %). The FTIR analysis revealed the presence of functional groups such as alcohols, ethers, esters, alkenes, carboxylic acid and amines. The XRD confirmed the crystalline nature of the synthesized CP-AgNPs. The synthesized AgNPs showed strong antibacterial activity against Escherichia coli (18.1±0.2 mm), Enterobacter sichuanensis (16.8±0.5 mm), Pseudomonas aeroginosa (14.4±0.3 mm), Staphylococcus aureus (22.2±0.5 mm) and Streptococcus agalactiae (21.5±0.1 mm). This study demonstrates an efficient, eco-friendly method for synthesizing AgNPs with strong antibacterial potential, which could be valuable for developing alternative antimicrobial agents.
