  • Bioreduction synthesis of zinc oxide nanoparticles using Delonix regia leaf extract (Gul Mohar) and its agromedicinal applications

    • Authors: Shabaaz Begum, J.P.; Manjunath, K.; Pratibha, S.; Dhananjaya, N.; Kashaw, Sushil (2020)

  • The bioreduction of Zinc nitrate hexahydrate using crude leaf extract of Gulmohar, by a combustion method at 400 °C was carried out to form the ZnO nanostructures. The structural, morphological and optic properties of the nanostructures were characterized by UV- Visible spectroscopy, XRD analysis, FTIR spectroscopy, SEM, and TEM. The antibacterial activity of pure wurtzite ZnO NPs was carried out by the Resazurin plate assay method followed by antifungal evaluation utilizing the food poisoning technique using bavistin as a positive control. The anticancer potential was performed using the HeLa cell line for the quantitative evaluation of MTT and apoptosis assay. Antibacterial effect o...

  • The present work reveals the green combustion preparation of the Ag-doped ZnO nanoparticles (NPs) using turmeric root extract as a fuel. The structure and morphology of Ag-doped ZnO NPs were investigated by several analytical techniques such as XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy), TEM (Transmission Electron Microscopy), FTIR (Fourier Transform Infrared), Raman, XPS (XRay Photoelectron Spectroscopy), and UV-Visible Spectroscopy (UVeVis). From XRD, the crystallite size was found to be about 45 nm which agrees with the TEM results. SEM micrographs reveal the spherical shaped agglomerated particles. XPS measurement anticipates that Ag is mainly in the metallic stat...
