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. The size and size distributions of the metals nanoparticles were examined by the transmission electron microscope TEM analysis. The nanoparticles concentrations were also characterized by atomic absorption spectroscopy AAS measurement.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.
