| Abstract Scope |
Green synthesis of metal nanoparticles presents a promising procedure for efficient and toxin-free nanomaterials. Copper oxide nanoparticles (CuO NPs) were synthesized with aqueous Canarium schweinfurthii leaf extract as a bio-reducing agent. The successful synthesis was confirmed using UV–visible spectroscopy (UV-VIS), Fourier Transform Infrared Spectrometry (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX) and X-ray Diffraction analysis (XRD). UV-VIS showed a characteristic peak around 260 nm for CuO NPs. FTIR revealed the various functional groups while the SEM showed their cubic and face-centred morphology. XRD confirmed the crystalline monoclinic structure of the CuO NPs, with a crystalline size of 30.81 nm. These CuO NPs exhibited outstanding antimicrobial activity against diverse microorganisms (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus aureus Bacillus subtillis, Candida albicans, Aspergillus niger). This study highlights the direct, cost-effective, non-toxic, and sustainable CuO NP synthesis. It offers insights into their potential applications in antimicrobial fields. |
