Abstract:
This study reports a facile, fast, eco-friendly, and one-pot approach for the synthesis of copper oxide nanoparticles (CuO NPs) using safe Pistacia vera peel extract. The extract is used as a stabilizing and reducing agent. Different analytical technique including FT-IR spectroscopy for determination of the Pistacia vera peel extract functional groups in the reduction and capping process of copper oxide NPs, UV–Vis absorption spectroscopy for affirmation of CuO presence, energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), and X-ray diffraction (XRD) was used in the present study. In these analyses, a sharp peak at ۲۸۳ nm in UV-vis tests, and a specific Ft-IR peak at ۶۰۱.۵۹ cm-۱ prove that this synthesis was completed using green chemistry principles. In addition, the average size of the biosynthesized nanoparticles was ۳۲.۹۷ nanometers according to the Scherrer equation. CuO NPs antibacterial activity was examined against Bacillus subtilis and Streptococcus pyogenes wherein CuO NPs, exhibited remarkable antibacterial activity with minimum bactericidal concentrations (MBCs) within the range of ۱۲۵-۱۰۰۰ 𝜇g/mL. Additionally, it showed better performance than classical antibacterials in the zone of inhibition assay against Bacillus subtilis. Generally, this study demonstrated that copper nanoparticles synthesized with plant mediators are completely competitive with other chemicals, such as drugs.
