In this work, synthesis, morpho-structural characterization, optical and antibacterial properties of zinc oxide nanoparticles have been reported. Zinc oxide nanoparticles were prepared at room temperature via green route using Coriandrum sativum leaf extract. The product was characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDX) and UV-Visible spectroscopy to ascertain its formation. Morphology study indicates spherical nature of the nanoparticles and the formation of zinc oxide nanoparticles was confirmed by EDX. XRD analysis showed crystalline nature of the ZnO with wurtzite structure having average crystallite size of 60 nm which was also corroborated by SEM and TEM analyses. Furthermore, the estimated band gap was 3.8 eV as determined by UV-Visible spectral analysis. Antibacterial efficacy of the prepared nano particles against the pathogenic bacteria E. coli reveals that the ZnO nanoparticles have considerably higher antibacterial potential and is possibly due to a combination of events. Besides, the outcomes of the synthesis certainly contribute to the developing a better understanding of simple, low-cost, green and nontoxic synthesis method and growing the knowledge base needed to design a suitable antibacterial materials and framework for advanced and wise applications.
