Zinc oxide nanoparticles were synthesized by a chemical method and characterized by various analytical techniques such as UV-visible spectroscopy, SEM-EDX, XRD, and FTIR. X-ray diffraction and SEM analysis confirmed the formation of well- dispersed zinc oxide nanoparticles with average particle size 22 nm as well as revealed their spherical structure. Chemically synthesized nanoparticles were found to exhibit antibacterial activity against bacterial strains Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus using agar well diffusion method of analysis.
