Abstract:Present study focuses on antifungal properties of copper oxide nanoparticles (CuO NPs) synthesized by hydro-thermal route. Copper (II) acetate was used as a precursor got reduced into stable CuO nanoparticles by controlled addition of reducing agent sodium hydroxide and capping agent Sodium Lauryl Sulphate (SLS). Characterization of CuO powder was carried out by using UV-Visible Spectroscopy and Scanning Tunneling Microscopy (STM). The absorption spectrum was found to be at 295 nm and its band gap about 2.1eV and STM image showed cluster morphology on surface at 50 nm. CuO NPs showed excellent antifungal activity against two molds Penicillium sp. and Rhizopus sp.Moreover, Penicillium sp.was found to be greater sensitive to CuO NPs compared to Rhizopus sp. However, probable antifungal mechanism of CuO NPs must be further investigated. Therefore, antifungal activity against Penicillium sp. and Rhizopus sp. molds reveals their effective potential in food security.

Keywords: Copper oxide nanoparticles, hydro-thermal synthesis, antifungal activity, Penicillium sp.and Rhizopus sp.
