The GO-ZnO nanocomposite was prepared by a facile wet chemical method to achieve superior antibacterial properties without damaging other species. The crystal phase, surface area, microscopic analysis of the GO-ZnO nanocomposites were studied by P-XRD, Raman spectroscopy, FE-SEM, HR-TEM, SAED and EDAX. In the composite, ZnO nanoparticles, with a size of about 5-10 nm, homogeneously anchored onto GO sheets. Antibacterial activity was evaluated using Aeromonas, Bacillus subtilis, Klebsiella and Pseudomonas aeuroginsa bacterial species. The results showed that the composite has a much stronger ability to kill bacteria at low concentrations.
