The antibacterial effect of zinc oxide (ZnO#1) as prepared and annealed (ZnO#2) at 400 o C, Cu doped ZnO (CuZnO), and Ag doped ZnO (AgZnO) nanoplates on Staphylococcus epidermidis was investigated for the inhibition and inactivation of cell growth. The results shows that pure ZnO and doped ZnO samples exhibited antibacterial activity against S. epidermidis as compared to tryptic soy broth (TSB). Also it is observed that S. epidermidis was extremely sensitive to treatment with ZnO nanoplates and it is clear that the effect is not purely depend on Cu/Ag. Phase identification of a crys talline material and unit cell dimensions were studied by Xray powder diffraction (XRD). The scan ning electron microscopy (SEM) provides information on sample's surface topography and the EDX confirms the presence of Zn, O, Cu and Ag. Xray photoelectron spectroscopy (XPS) was used to analyze the elemental composition and electronic state of the elements that exist within the samples. These studies confirms the formation of nanoplates and the presence of Zn, O, Ag, Cu with the oxida tion states +2, 2, 0 and +2 respectively. These results indicates promising antibacterial applications of these ZnObased nanoparticles synthesized with lowcost hydrothermal methods.
