Abstract


The present work portray the Aspidopterys Cordata (AC) leaf extract-assisted fabrication of zinc oxide nanospheres (ZnO NSs) using an eco-friendly approach for antibacterial and antioxidant activity. As fabricated ZnO NSs were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), energy dispersive X-ray diffraction (EDX), UV-Visible diffuse reflectance spectroscopy (UV-DRS), Raman, X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), and transmission electron microscope (TEM) for authenticate the structure, shape, size, chemical state, and morphological facet. XRD pattern showed the strong and intense diffraction peaks indicating the formation of crystalline ZnO NSs with hexagonal phase. Further, EDX revealed the formation of highly pure ZnO with signals of Zn and O elements. UV–DRS reveals absorption band at 370 nm, assigned to the intrinsic band-gap absorption of ZnO, owing to the electron transitions from valence band to conduction band. TEM images inveterate the formations of ZnO NSs with mean particle size of 11.6 nm. The antibacterial activity of ZnO NSs was examined against gram-positive (Staphylococcus aureus) and gram-negative (Proteus vulgaris, Escherichia coli, and Klebsiella pneumonia) human pathogenic bacteria using ZnO NSs by agar-well diffusion method. Furthermore, ZnO NSs exhibited significant antioxidant activity against scavenging 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) free radicals.
