a) In vitro cytotoxicity of Mo@Fe‐ICG against L929 cells after 24 h incubation. b) Flow cytometry analysis of Hela cells under different 808 nm NIR irradiation power densities (b₁: 0 W cm⁻²; b₂: 0.5 W cm⁻²; b₃: 1.0 W cm⁻²) after incubated with Mo@Fe‐ICG/Pt (100 × 10⁻⁶ m of Mo). c) In vitro cytotoxicity of MoS₂@Fe₃O₄, MoS₂@Fe₃O₄+NIR, Mo@Fe‐ICG, Mo@Fe‐ICG+NIR, Mo@Fe‐ICG/Pt, and Mo@Fe‐ICG/Pt+NIR against HeLa cell after 24 h incubation. The cells were either exposed to 808 nm laser (1.0 W cm⁻²) for 5 min or not. d) JC‐1 probes were used as the mitochondrial membrane potential indicator through comparing the fluorescence intensity ratio of red and green. The incubation concentration of Mo@Fe‐ICG/Pt is 100 × 10⁻⁶ m and the 808 nm NIR irradiation power density is 1.0 W cm⁻².
