In the recent years, these green syntheses of nanoparticles have emerged as important role in medicinal and industries etc. With green synthesis we can prevent environment pollution and formation of toxins. The antimicrobial agents like silver nanoparticle synthesis were applied in the study of dried leaves extract of Azadirachtaindica. The plant leaf serves as a reducing and capping agent at the same time. The various techniques like SEM and TEM are used to characterize synthesised silver nanoparticles.To identifying the functional group present in the dried leaves extract through the FTIR spectrometer by the reduction of silvers ions. The surface morphology of dispersed nanoparticles studied by using SEM. The TEM displaying the mono dispersion and size range of the silver nanoparticles. The procedure for silver nanoparticles at room temperature is quick and effective, but finding the exact dose in water purification is difficult.
