Synthesis of Zinc Oxide Nano Powder and its Characterization Using XRD, SEM and Antibacterial Activity Against Staphylococcus aureus

Nanoparticles have attracted much attention for their distinct characteristics that are unavailable in conventional macroscopic materials. Their uniqueness arises specifically from higher surface-to-volume ratios and an increased percentage of atoms at the grain boundaries.ZnO nanoparticles in the size range 41nm have been synthesised by a wet chemical method where ZnO particles were grown in basic Zinc nitrate hexahydrate and NaOH solution.  The particle size given from XRD measurements has been developed and compared to other similar relations found in the literature. SEM is used toanalyze the morphological size of nanoparticle. Scanning Electron Microscopy (SEM) is used primarily for the study of surface topography of solid materials.Zinc oxide nanoparticles can enhance the antibacterial activity of Staphylococcus aureus enhancing effect of this nanomaterials concentration is dependent against test strain.
