The present work was undertaken to develop silver nanoparticles by a simple chemical route using harmless surfactant polyvinylpyrrolidone (PVP) at four different temperatures viz., 200 °C, 300 °C, 400 °C and 500 °C. Effect of temperature on structural, morphological and antibacterial properties was investigated. The XRD pattern confirmed the crystallinity and pure phase of the Ag-NPs. Also it is confirmed that the size of the Ag[PVP] nanoparticles was affected by the temperature. The FT-IR analysis indicated the functional groups of PVP coordinate with silver ions and bind on surface of Ag-NPs. EDAX confirmed the formation of Ag nanoparticles without a trace of impurities. The SEM images showed the formation of spherical Ag[PVP] nanopowder in which the average particle size ranges from 20 nm to 34 nm. The antibacterial potential of synthesized Ag[PVP] nanoparticles was carried out against four different bacterial pathogens and show significant bacterial resistance.
