• The MoS₂ nanosheets served as co-catalyst could reduce Fe³⁺ ions with lower Fenton reaction activity into the highly reactive Fe²⁺ ions, thereby boosting the production of hydroxyl radical (•OH) for high efficiency chemodynamic therapy (CDT).

• The photothermal effect of MoS₂ nanosheets motivated by second near-infrared light could further improve the treatment effectiveness by synergetic photothermal-enhanced CDT and photothermal therapy.

助催化协同效应和第二近红外光引发的光热效应促进化学动力治疗

• 
  MoS ₂纳米片作为助催化剂可以将芬顿反应活性较低的Fe ³⁺离子还原为高活性的Fe ²⁺离子，从而促进羟基自由基（·OH）的产生，用于高效化学动力学疗法（CDT）。

• 
  由第二近红外光激发的MoS ₂纳米片的光热效应可以通过协同光热增强CDT和光热疗法进一步提高治疗效果。
