Punica granatum flower extract mediated synthesis of Copper oxide Nanoparticle and evolution of its antibacterial activity
Publication Date : 12/01/2018
Nano copper oxide is extensively used as an important inorganic material in variety of fields such as catalysis, superconductors, ceramics etc. Owing to its characteristic properties, such as photovoltaic properties, thermal resistance and antioxidant activity it has achieved a huge applications compared with the ordinary copper oxide. In this paper, we report the green synthesis of copper oxide nanoparticle making use of eco-friendly Punica granatum flower extract. The synthesized CuO NPs are characterized by UV-visible absorption spectroscopy, fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). The UV absorption band at 442 nm confirms the formation of CuO NPs and XRD pattern confirms the crystalline monoclinic structure of CuO NPs. FT-IR reveals the presence of variety of phytochemicals like terpenoids, alkaloids, phenolic along with CuO NPs as capping agents. The synthesized CuO NPs exhibit very good anti bacterial activity of towards both gram positive and negative pathogens.
