Abstract

In this paper, Au NPs prepared by pulsed laser ablation in liquid (PLAL)  with different laser energy (200, 360,500,660 and 800 m J) with number of pulses (1000pulse), at wavelength 1064 nm, and repetition rate of 1Hz. The structural, morphological and optical properties were discussed. XRD spectra showed the diffraction peak. AFM showed the average diameter. The optical properties showed increase absorption spectra at increase energy. Further in vitro antibacterial activities of Au NPs were investigated against Gram positive and Gram negative. Staphylococcus aureus  and E.Coli. Studied Toxicity of the synthesized Au NPs on human blood cells.
