Abstract
Silver Nanoparticles (Ag NPs) have strong antibacterial activities, for that it is very useful for medical applications. Stable silver nanoparticles were synthesized using sodium borohydride (NaBH4) and PVP as reducing and stabilizing agent respectively. Their shape and size distribution characterized by UV-vis spectrophotometer, scanning electron microscopy (SEM) equipped with the energy dispersive spectroscopy (EDS) and (TEM) transmission electron microscopic study their shape and size(< 20nm). The activity of Ag nanoparticles was investigated against isolated bacteria invading the blood' stream by agar diffusion method. The synthesized AgNPs show the ability to discourage the growth of the tested bacteria, which show high activities against most of the tested isolate of G(+) ve bacteria and G(-) ve bacteria that invading the blood stream. The current approach described rapid synthesis of silver using NaBH4 and PVP as reducing and stabilizing agents, respectively. This would be suitable for developing a process for discouraging the pathogenic bacteria activities.
