Hydrothermal synthesis of Copper nanoparticles, characterization and their biological applications

Abstract

We report an ecofriendly novel method for copper nanoparticles (CuNPs) synthesis by hydrothermal processes using an activated carboxymethyl gum of locally available medicinal plant <em>Cochlospermum gossypium</em>as capping agent. The synthesized CuNPs characterized by Ultraviolet - visible Spectroscopy (UV-Vis), Fourier – transform infrared Spectroscopy (FTIR), and Transmission Electron Microscopy (TEM) and X-ray diffraction techniques (XRD). The XRD results showed a face-centered cubic structure with (111) as the prepared orientation. The CuNPs showed good antibacterial and antifungal activity against pathogenic strains like <em>E</em><em>.</em><em> coli,</em><em> Bacillus cereus, Bacillus subtilis </em>and <em>Candida albicans, Candida parapsilosi, </em><em>Aspergillus Niger </em>and <em>Aspergillus oryzae</em> respectively. A result of this study indicates that the CuNPs has remarkable potential antimicrobial property. It will be used in treating infectious diseases and also use full in biomedical application.
