| Abstract | ||
| Gold and silver nanoparticles colloids were produced by irradiating a metallic target plates with a thickness of 1mm immersed in distilled water with a pulsed laser beam. Antibacterial properties of silver and gold nanoparticles are attributed to their total surface area, as a larger surface to volume ratio of nanoparticles provides more efficient means for enhanced antibacterial activity. Gold and silver nanoparticules was reducing gram positive and gram negative bacterial growth . Staphylococcus was revealed more inhabition zone than Streptococcus ,and E.coli | ||
