Biogenic synthesis of copper oxide nanoparticles using leaf extracts of <i>Cissus quadrangularis</i> and <i>Piper betle</i> and its antibacterial effects

Owing to its environment-friendly, biocompatible, non-toxic nature of nanoparticles attained from green plant extract, it has remarkable significance in the field nanotechnology towards effective biomedical application. This work reports synthesis copper oxide by means Cissus quadrangularis and Piper betle via green-synthesis route. The medicinal leaf extracts possessing phytochemicals such as alkaloids polyphenols act a reducing agent current synthesis. characterization functional groups CuO NPs two different was investigated FTIR analysis which measures reduction stabilization NPs. X-ray diffraction confirms orthorhombic structure with an average crystallite size about 32.54 32.09 nm. irregular spherical-shaped morphology samples is evidenced scanning electron microscopy analysis. transmission images demonstrated 50 nm sized prepared nanoparticles. bioactivity sample confirmed antibacterial studies zeta potential.
