(a) Schematic illustration of single-layered MoS₂-based nanoplate as a NIR-responsive system. NIR-induced cytotoxicity of DOX-PSMS-PEG or PSMS-PEG against (b) HeLa and (c) HCT-8 cell line (**p < 0.01, ***p < 0.001). (d) Confocal microscopic images of DOX-PSMS-PEG treated HeLa cells which were further irradiated or not irradiated by 808 nm laser (5 W/cm²). Nucleus was stained by DAPI (blue) and DOX was false-imaged as red (scale bar = 50 μm). (e) Photoresponsive drug release of DOX from DOX-PSMS-PEG in vitro. Reprinted with permission from Ref. [206].
