Zinc oxide (ZnO) nanoparticles have been synthesized via microwave-assisted method. The structural analysis was carried out using X-ray diffractometer. It showed that the ZnO nanoparticle exhibited hexagonal structure. Further the ZnO product was investigated by FT-IR and SEM analysis. Also antimicrobial efficiency in different concentrations have been studied and found good activity against Escherichia coli.
