Our research focused on the production, characterization and application of silver nanoparticles (AgNPs), which can be utilized in biomedical research and environmental cleaning applications. We used an environmentally friendly Green synthetic technique for the production of the AgNPs. The Vitex negundo leaf extract used to produce the nanoparticles were from aqueous extracts. Synthesis of colloidal AgNPs was monitored by UV-Visible spectroscopy. The UV-Visible spectrum showed a peak between 410 nm corresponding to the Plasmon absorbance of the AgNPs. The method used for the preparation of silver nanoparticles was found to be rapid and require no toxic chemicals. The Vitex negundo capped silver nanoparticles were characterized by UV/Vis-spectroscopy, Particle size analyzer (PSA), Transmission electron microscopy (TEM) and Energy dispersive X-ray Analysis (EDX). Duly characterized nanoparticles were explored for their application as antimicrobial agent were also found to exhibit reasonably good antimicrobial activity when compared with standard Chloramphenicol, which suggests its potential use as antimicrobial agent with Gram-negative and Gram-positive bacteria, which is not toxic for human healthy cells, but inhibit bacterial growth.
