A gold cluster fused manganese dioxide nanocube loaded with dihydroartemisinin for effective cancer treatment amplified oxidative stress.

Chemodynamic therapy, leveraging metabolic processes for reactive oxygen species (ROS) generation, shows promise in cancer eradication. However, its efficacy is hampered by hypoxic conditions, substrate scarcity, and abundant ROS scavengers. In this study, we have devised a cubic manganese oxide nanozyme (BSA-AuNC-MnO@DHA) to tackle these obstacles.
