Nanotechnology is a research hot spot in modern material science. Zinc oxide nanoparticles (ZnO NPs) are known to be one of the most multifunctional inorganic nanoparticles which have potential antimicrobial activity. Present study states a green approach for the synthesis of ZnO NPs employing aqueous extract of Ocimum tenuiflorum leaves. Leaves extract was used as the biological reducing agent for synthesizing ZnO NPs and were characterized by UV-Visible spectroscopy (UV-Vis), X-ray diffractometer (XRD) and Scanning Electron Microscopy (SEM). UV-Visible spectrum peak was obtained at 365nm clearly demonstrating the presence of ZnO NPs. XRD exhibited 2θ values corresponding to ZnO and particle size was estimated to be 100nm. ZnO NPs were tested for their antibacterial potential and found to be active against Staphylococcus aureus and Escherichia coli. Citric acid/ZnO NPs composite bandage was developed by impregnating it with the mixture of citric acid and ZnO NPs. The prepared composite bandage showed excellent antibacterial activity against Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae. Hence an easy and effective green approach for synthesis of ZnO NPs with its biomedical capability is indicated in this study.
