Copper oxide nanoparticles (CuO NPs) offer unique properties driving diverse applications. Their potent antimicrobial activity is highly valued. CuO NPs effectively disrupt bacterial and fungal cell membranes and generate reactive oxygen species, making them powerful agents in medical devices, wound dressings, antimicrobial coatings for surfaces, and even agricultural formulations to combat plant pathogens. In catalysis, their high surface area and reactivity are key. CuO NPs serve as efficient catalysts or catalyst supports in numerous chemical reactions, including organic synthesis transformations, carbon monoxide oxidation, and pollutant degradation processes. Sensing applications leverage their electrical and optical characteristics. CuO NPs are integrated into sensors for detecting gases like carbon monoxide and hydrogen sulfide, as well as various biological molecules and environmental contaminants, offering high sensitivity and selectivity. Energy applications are significant. CuO NPs show promise in solar energy conversion, acting as light absorbers or charge transporters in photovoltaic cells. They are also explored for enhancing lithium-ion battery anode performance due to their high theoretical capacity. Environmental remediation utilizes their catalytic and adsorptive powers. CuO NPs effectively degrade organic pollutants like dyes and pesticides in wastewater through photocatalysis or chemical reduction. They also adsorb heavy metal ions from contaminated water sources. Their versatility, combined with relatively straightforward synthesis, makes CuO nanoparticles crucial across biomedical, industrial, sensing, energy, and environmental fields.
