Boosting Chemodynamic Therapy by the Synergistic Effect of Co-Catalyze and Photothermal Effect Triggered by the Second Near-Infrared Light

The MoS 2 nanosheets served as co-catalyst could reduce Fe 3+ ions with lower Fenton reaction activity into the highly reactive Fe 2+ ions, thereby boosting the production of hydroxyl radical (•OH) for high efficiency chemodynamic therapy (CDT). The photothermal effect of MoS 2 nanosheets motivated by second near-infrared light could further improve the treatment effectiveness by synergetic photothermal-enhanced CDT and photothermal therapy.
