A HPLC chromatogram of the IR820-SS-CPT NPs in the presence of GSH (10 mM). B HRMS spectrum of the products from the reaction of IR820-SS-CPT with GSH (10 mM) in DMSO/H₂O (1:99, v/v). C In vitro CPT release from the IR820-SS-CPT or IR820-CC-CPT NPs in the presence of various amount of GSH. D Temperature increase profiles of IR820, IR820-SS-CPT NPs, IR820-SS-CPT NPs + GSH, IR820-CC-CPT NPs, and IR820-CC-CPT NPs + GSH with laser irradiation for 5 min (IR820-SS-CPT NPs: 660 nm, 1.0 W/cm²; IR820: 808 nm, 1.0 W/cm²). The equivalent IR820 dose was kept at 100 µM
