Abstract

The present study was aimed at the biosynthesis of zinc oxide nanoparticles (ZnONPs) using aqueous stem extract of Dendrophthoefalcata and testing their antioxidant and antibacterial activity. The green synthesized ZnONPs were characterized using UV-Visible spectrophotometer, Fourier transform infrared (FTIR) spectrophotometer, Scanning electron microscope (SEM), X-ray diffraction (XRD) and Atomic force microscopy (AFM). The ZnONPs showed better antioxidant and antibacterial activity against DPPH radical scavenging and gram positive bacteria respectively.
