Synthesis of biocapped CuO nanoparticles: An investigation on biorganic-Cu2+ interactions, in vitro antioxidant and antimicrobial aspects

The present research reports an eco-friendly, cost-effective, rapid, and easy method for preparing CuO nanoparticles (CuONPs) using the fruit extract of rose hip as a biocapping and reducing agent. The CuONPs are crystalline in nature and possess average sizes near 40 nm. Next, the biorganic-Cu2+ interactions were investigated based on FT IR results, X-Ray diffraction patterns, and potentiometric data during capping of cupric species. The free-radical scavenging potential of CuONPs as well as their antibacterial activity was tested against four pathogenic microbes. The CuONPs prepared from rose hip fruit metabolites showed promising results, accordingly proving their biomedical importance.
