Nowadays, the researchers search in their studies for new antimicrobial agents which have the unique physical and chemical properties. In this experiment, AgNPs solution was synthesized by chemical reduction, characterized and tested as the antibacterial effects of sliver nanoparticles (Ag-Nps ) on S. aureus. Sliver nanoparticles revealed unique physical and chemical properties that suitable to understand to possess a broad spectrum of antimicrobial activities. Sliver nanoparticles (AgNPs ) characterized by UV- Visible spectrphotometry by exhibiting the typical surface plasmon absorption maxima at 400 nm. The morphology of the sliver nanoparticles was measured by Scanning Electron Microscope (SEM. (Investigating Antimicrobial activity of nanoparticles were evaluated by using Minimum Inhibitory Concentration ( MIC) technique. The experiment results showed that the lowest MIC and MBC of Ag-NPs to S. aureus was 30 ppm, 300ppm, respectively. The obtained results suggested that Ag-NPs exhibit bacteriostatic and bacteriocidal effect towards S.aureus.The present study indicates (AgNps) has considerable antibacterial activity.
