Present work deals with a simplistic surfactant assisted combustion synthesis of ZnO NPs (Zinc Oxide Nanoparticles) where Zinc nitrate solution is used as a precursor and Glycine as fuel with TWEEN 80, a non ionic surfactant. Characterizations carry out 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 Transmission Electron Microscope, and particle size by Particle Analyzer. Antimicrobial activity of ZnO Nanoparticles against Staphylococcus aureus and Escherichia coli has been tested by disc diffusion technique. ZnO Nanoparticles exhibited a very strong antibacterial activity against bacterial species.

Keywords: ZnO Nanoparticles, surfactant assisted, TEM, Staphylococcus aureus, Escherichia coli antibacterial activity.
