ABSTRACT

The goal of this study is to compare the optical, morphological, and antibacterial properties of ZnO nanoparticles (NPs) made using chemical and green methods. Fourier transform infraredspectroscopy (FTIR), dynamic light scattering (DLS), Ultraviolet-visible spectroscopy (UV-Vis), Scanning electron microscope (SEM), and X-ray diffraction (XRD) were used to characterize the nanomaterials. Both gram-positive and negative microorganisms were tested for antibacterial activity. Density functional theory (DFT) calculations clearly indicate that quercetin is mainly responsible for the stabilization and reduction of ZnO NPs. Plant-mediated nanomaterials have been found to be a more promising candidate for use in a variety of medicinal and industrial research sectors than chemically synthesized nanoparticles.
