Role of Green Synthesized CuO ‎Nanoparticles of Trigonella Foenum-‎Graecum L. Leaves and their Impact on ‎Structural, Optical and Antimicrobial ‎Activity ‎

The present research work focused on the synthesis, characterization and testing of antimicrobial activity of CuO nanoparticles prepared by green synthesis method using Trigonella foenum-graecum L. leaf extract. The XRD pattern indicated the presence of cubic structure of nanocrystalline CuO with crystallite size of 47 nm. The optical band gap was calculated using Tauc’s plot and found to be 3.6 eV. SEM images revealed that the particles had cluster structures with a combination of different shapes. EDAX analysis confirmed the presence of copper and oxide by indicating predominant peak which was the highest percentage present in the spectrum. The synthesized nanoparticles showed significant antibacterial and antifungal activity against the human pathogens Staphylococcus aureus and Penicillium sp. So this nanoparticle can be considered as an alternate approach for reducing the adhesion of micro-organisms.
