Copper (II) oxide nanoparticles are successfully synthesized with the green synthesis method on the experiments we performed.  UV-VIS spectroscopy of the characterization of acquired CuO NPs were performed with Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). Optimum activation temperature for green synthesis was observed to be in 30 min, pH:8, at 25 <sup>o </sup>C and in the concentration of 1mM CuCl <sub>2 </sub>. By using peroxidase enzymes with green synthesis, it was found out the results of SEM and XRD measurements that acquired CuO NPs were in the size of 50-120 nm. Afterwards, the antioxidant and antibacterial activities of these nanoparticles were measured and it was understood from the obtained results that CuO NPs had both antioxidant and antimicrobial activities. </p>}, number={3}, publisher={Turkish Chemical Society}
