Optimization of organic dyes photodegradation and investigation of the anticancer performance by copper oxide/graphene oxide nanocomposite

This study investigates the enhancement of organic dye photodegradation and evaluates the anticancer potential of a copper oxide/graphene oxide nanocomposite, thereby furthering environmental remediation and biomedical applications. This study aims to bridge the divide between environmental remediation and biomedical advances by optimizing the photodegradation of organic dyes using a copper oxide/graphene oxide nanocomposite while investigating its potential anticancer properties. The as-prepared nanocomposites were characterized using several methods, such as HRTEM, FTIR, XRD, and XPS spectroscopy. The GO@CuO nanocomposite was utilized to adsorb and photodegrade Rhodamine-B (RhB) and Malachite green oxalate (MGO) from an aqueous solution. The GO@CuO nanocomposite exhibits considerably enhanced adsorption and photodegradation when exposed to visible light compared to when it is kept in the dark. The GO@CuO compound displayed a remarkable ability to remove 84.77% of RhB and 87.81% of MGO for a duration of 60 min. RhB and MGO are resistant to adsorption alone, but photodegradation under visible light is more efficient. The anticancer activity of GO@CuO nanocomposites was shown to be considerable when examined on the ACHN cancer cell line. The results indicate that GO@CuO nanocomposites have the potential to be an innovative cancer treatment. The study concludes that the copper oxide/graphene oxide nanocomposite exhibits remarkable efficacy in both organic dye photodegradation and anticancer activity, offering a promising multifunctional material for diverse applications. The novelty lies in the synergistic combination of environmental and biomedical capabilities within a single nanocomposite, opening new avenues for sustainable and therapeutically relevant materials.
