Zinc oxide nanoparticles (ZnO) were synthesized by using a simple chemical sol-gel precipitation method with zinc acetate and sodium hydroxide in distilled water as a starting material. The synthesized sample was calcinated at different temperature for 1hour and different morphological changes occurred in samples were observed. The samples were characterized by X-ray diffraction (XRD), Scanning Electron Microscope (SEM) which showed various morphological changes of ZnO. UV shows absorption spectra of ZnO nanoparticles. ZnO nanoparticle has shown a wide range of antibacterial activity. ZnO nanoparticle inhibits the growth of Bacillus thuringiensis NCIM2130 upto 30 mm and Pseudomonas cf. monteilii 9 upto 20 mm which more effective than the antibiotic used for comparative testing.
