Investigating the antibacterial activity of Zinc Oxide Nanoparticles against staphylococcus aureus isolates

In the current research, Zinc oxide nanoparticle solution was prepared at different concentrations. A minimum particle size between (52.31 - 134.3 nm) was obtained. The structural and optical properties were determined as functions of concentration. Results of the Field Emission Scanning Electron Microscopy (FE-SEM) indicated that as the concentration of zinc oxide nanoparticles decreased, their size also decreased. Antibacterial activity for Zinc Oxide nanoparticles was tested by the extent of killing Staphylococcus aureus isolates, and using a lower Zinc Oxide nanoparticle concentration revealed 50% more activity than higher concentrations.
