Biosynthesis of CuO Nanoparticles Using Plant Extract as a Precursor: Characterization, Antibacterial, and Antioxidant Activity

Biosynthesis of metal nanoparticles presents a promising approach for their efficient and environmentally friendly production. In this study, CuO were successfully synthesized by using Rumex nepalensis Spreng. as bio-reducing agent. The spectroscopic analysis confirmed the crystalline monoclinic structure NPs, with particle sizes ranging from 21 to 97 nm. These biosynthesized NPs exhibited notable antimicrobial activity against diverse microorganisms, suggesting potential applications. Moreover, displayed significant antioxidant activity, demonstrated effective scavenging 1,1-Diphenyl-2-picrylhydrazyl (DPPH) free radicals. This study highlights straightforward, cost-effective, non-toxic, robust nature synthesis Spreng., offering insights into applications in fields.
