Synthesis and Characterization of Zinc Oxide Nanoparticles Using Moringa Leaf Extract

This paper investigates the technique of biosynthesis of nanoparticles of zinc oxide from the extraction of moringa leaves. Many researchers recognize the use of this method of green culinary technique because it is cost-effective and has no negative impact on the environment; however, this paper focuses on the bacteria chosen for the green synthesis, which was not addressed by many of the researchers. The firmness and reduction of Zn ions in nanoparticles of zinc oxide were analyzed with a UV-visible spectroscope. Its results show that a wide bandgap was observed in the visible region at a wavelength of 350 nanometers. Extraction of moringa leaves serves as a promising agent for the balance of particle size. The result of medical value shows significant antibacterial activity in contrast to the type of pathogenic bacteria Escherichia coli and Staphylococcus aureus. From the XRD results, there are no further peaks that correspond to impurities that are discovered, demonstrating the great purity of the provided results.
