The research was carried out to investigate the synthesis of silver nano particles. The silver nano particles have wide tremendous application in the therapeutics, antimicrobials, diagnostics, catalysis, micro-electronics and high sensitivity biomolecular detection. Silver nano particles grow in a single-step method, at room temperature, and with no addition of external energy. The silver nanoparticles were synthesized from silver nitrate aqueous solution through a simple, ecofriendly and cost effective course using the leaf broth of the Oscimum sanctum, Azadirachta indica and Lawsonia Inermis (kadvi mehndi), therefore calling it green synthesis. The Synthesized AgNP was confirmed by sampling the aqueous component at different time intervals and the absorption maxima was scanned by UV-Vis spectrometry and Particle Size Distribution (PSD). Based on PSD, the particles were further characterized by Scanning Electron Microscope. Synthesized AgNP was confirmed at 531,540and 543 nm. Among the total percentage of size distribution, D-50 value, which is 50% size distribution, was taken into consideration, where the size of the nanoparticle was established to 0.135µm. Further research is going on with reference to the synthesized nanoparticles.
