The investigation of antibacterial activity and cell viability of rGO/Cu2O nanocomposite

With pathogenic microorganisms such as bacteria around our lives, research and finding an effective antibacterial agent is essential. This study prepared and developed a novel nanocomposite based on photocatalytic properties. For grafting of copper (I) oxide nanoparticles in reduced graphene oxide sheets, the simultaneous reduction reaction of graphene oxide and copper (II) acetate monohydrate salt in the presence of sodium borohydride was used to reduce agent. Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), Energy-dispersive X-ray (EDAX), and Raman spectroscopy studied and identified the prepared nanocomposite. These studies showed that 2D rGO is well-decorated by Cu2O nanoparticles. The results of antibacterial tests showed that the synthesized nanocomposite has excellent antibacterial properties, and due to exposure to UV light for 6 h, these properties have been increased. Also, the toxicity of nanocomposite indicated that this agent had biocompatibility properties.
