The characterization of TST nanoparticles. A) The temperature change of water, TST‐Sol, DSPE‐NP, and CAT‐NP under 808 nm laser irradiation at 1 W cm⁻². B) The temperature change of CAT‐NP under different power of 808 nm laser irradiation. C) The temperature change of CAT‐NP with different concentrations under 808 nm laser irradiation at 1 W cm⁻². D) The temperature change of CAT‐NP during three consecutive 808 nm laser irradiation and cooling cycles. E) The nanoparticle size measured by dynamic light scattering (DLS) and transmission electron microscope (TEM) images of CAT‐NP, scale bar: 200 nm. F) Emission fluorescence intensity curves of TST‐Sol, DSPE‐NP, and CAT‐NP at the same concentration after excitation with 808 nm laser. G) The NIR‐II images of TST‐Sol, DSPE‐NP, and CAT‐NP at the same concentration after excitation with 808 nm laser. H) The CPT release profile of C‐NP in 1 mm H₂O₂ and 10 mm H₂O₂ (n = 3). I) Photothermal images of water, TST‐Sol, DSPE‐NP, and CAT‐NP irradiated by 808 nm laser at 1 W cm⁻².
