| Summary: | The investigation aims at the synthesis of copper oxide nanoparticles (CuO Nps) using Gloriosa superba L. plant extract as fuel by solution combustion synthesis, their characterization and studies on antibacterial activities against selected pathogenic bacteria. X-ray diffraction studies showed that the particles are monoclinic in nature. The UV–visible absorption spectrum of CuO Nps indicates the blue shift with increase of concentration of plant extract. SEM images reveal that the particles are spherical in nature. TEM image indicates that as-formed CuO Nps are spherical in shape, and the size is found to be in the range 5–10nm. Further, as-formed CuO Nps exhibit significant antibacterial activity against pathogenic bacterial strains namely Gram −ve Klebsiella aerogenes, Pseudomonas desmolyticum, and Escherichia coli, Gram +ve bacteria Staphylococcus aureus. The current study demonstrates convenient utilization of Gloriosa superba L. extract as a fuel for the efficient synthesis of CuO nanoparticles through a green synthesis method to obtain significantly active antibacterial material. |
