In this article, a simple new technique for the green synthesis of copper oxide nanoparticles (CuO NPs) using peroxidases oxidoreductases (POX) enzyme extracted from fig leaves for antifungal and antibacterial activities has been reported. Subsequently, a comprehensive investigation of the structural, optical, and morphological properties of the synthesized CuO NPs was elucidated, using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Electrodiagnostic (EDX), atomic force microscopy (AFM), and transmission electron microscopy (TEM) analysis techniques. Specifically, the resultant nanoparticles are spherical with a diameter ranging from 28–68. CuO NPs were further tested for their antifungal activity against Candida and Aspergillus species, while the antibacterial activity was screened in contradiction of pathogenic bacterial strains namely gram-positive Staphylococcus aureus and gram-negative Asinobacterial species. The present study reveals a convenient use of POX fig leaves extract as fuel, for the well-organized synthesis of CuO NPs via green synthesis technique to acquire considerably active antifungal and antibacterial materials.
