This study shows the effect of silver nanoparticles (Ag-NPs) or He-Ne laser (2mw) each of them individually, on Staphylococcus Aureus (S. aureus); also study the dual effect of nanoparticles and laser energy to kill or inhibition of bacterium. He-Ne laser with different time of irradiation and Ag-NPs with different concentrations were used against S. aureus bacterium. The results showed that S. aureus was affected by Ag-NPs especially in high concentration and there was a little effect of He-Ne laser on bacterial growth.
