Abstract The rapid one-pot synthesis of silver nanoparticles (SNPs) at room temperature by using hydrazine hydrate as reducing agent and polyvinyl alcohol as stabilizing agent is reported. The SNPs were characterized with UV-visible (UV-Vis) spectroscopy, x-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM) and transmission electron microscopy (TEM). The synthesized silver nanoparticle shows surface plasmon resonance at 410 nm. The XRD reveals face-centered cubic (FCC) structure of SNPs. FE-SEM, AFM and TEM show that nanoparticles have spherical morphology with diameters in the range of 10–60 nm. The antimicrobial activity of synthesized hybrid material against strains of four different bacteria ( Bacillus cereus, Escherichia coli, Staphylococus aureus, Proteus vulgaris ), that are commonly found in hospitals has been studied. The results indicate that such particles have potential applications in biotechnology and biomedical science.
