[en] Development of eco-friendly biosynthesis process for the synthesis of stable silver Nanoparticles is congregating researchers since past few years. In this study eco-friendly synthesis of stable silver Nanoparticles was done by using Phaseolus vulgaris seeds extract. The formation of nanoparticles was characterized by visual observation followed by UV-Vis spectrophotometric analysis, which showed a peak around 450 nm, which is very specific for silver nanoparticles. Further analysis carried out by Fourier Transform Infrared Spectroscopy (FTIR), provides evidence for the presence of proteins as capping agent, which helps in increasing the stability of the synthesized silver nanoparticles. All the three plant extracts were found to exhibit strong potential for rapid reduction of silver ions. The synthesized nanoparticles are then analyzed for their potency in medical applications. Biosynthesis of nanoparticles are proving to be more effective in medicinal applications than the bare metal nanoparticles since the biomass coatings on them act synergistically with the metal nanoparticles.
