In the present paper we report the antibacterial activity of Zinc Oxide Nanoparticles (ZnO NPs) which are prepared by a facile surfactant assisted combustion synthesis where Zinc nitrate solution is precursor and Urea as fuel with TWEEN 80, a non ionic surfactant. Antimicrobial activity of ZnO Nanoparticles against five bacteria Xanthomonas, Serratia, Pseudo Vulgaris, Bacillus subtilis and Staphylococcus have been tested by disc diffusion technique. ZnO Nanoparticles exhibited a very strong antibacterial activity against bacterial species. The microbial property of ZnO nanoparticles was analyzed by measuring the inhibition zone. ZnO NPs were characterized in order to study different properties of the acquired particles the crystalline size and shape analysis by X-ray diffraction, UV-Vis absorption spectroscopy to monitor peak absorbance wavelength and nanoparticles size determined by using the mathematical model of effective mass approximation equation, Thermogravimetric (TG) analysis for weight loss, surface morphology by Scanning Electron Microscope, and particle size by Particle Analyzer.
