Preparation Sliver Nano Particles (AgN) Via Laser Ablation And Bacteria Effect

In this research, Nano silver(AgN) was prepared by pulse laser ablation liquid technique(PLAL) with different laser energies (550,650,700) mJ and different pulses (300,600,900) pulse. The properties of Nano silver were studied for tested likes X-ray diffraction(XRD), and it was found sliver Nano particles has a face center cubic. It was also found from examination scanning electromagnetic (SEM) that it has a spherical shape with nanometer sizes reaching less than 20 nanometers, when the test of Zeta potential(Z-potential) proved sliver Nano particles were stability. From the biological side, Nano silver has proven its ability to inhibit bacteria from diffusion.
