| description | Zinc oxide, a well-known inorganic metal oxide in nanoparticle form, has outstanding antibacterial properties. In this work, the
authors focus on determining ZnO nanoparticles’ structural, optical, and antibacterial activity. A simple soft chemical route
synthesizes C-ZnO nanoparticles chemically, while the green synthesis method is used to prepare G-ZnO nanoparticles. Ocimum
tenuiorum leaf extract was used to prepare G-ZnO nanopowders. ese samples are investigated and compared in terms of their
structural, morphological, optical, and antibacterial properties. According to XRD investigations, the synthesized ZnO nano-
powders possess a hexagonal structure. e particle size of G-ZnO is smaller than that of C-ZnO nanoparticles. e XPS result
revealed the binding and interactions between molecules. e FTIR study conrmed the presence of molecules and their vi-
brations. UV-vis-DRS spectroscopy was used to investigate optical properties such as reectance and band gap. e grain size of
the G-ZnO nanopowders was decreased, and oxygen vacancy was produced. e antibacterial eciency of plant extracts against
two dierent bacterial strains, S. aureus (Gram-positive) and E.coli (Gram-negative), has been studied and reported. |
