Photothermal and photodynamic performance of ZnO₂@Lip-ICG. (A) Thermographic images and (B) temperature elevation profiles of different solutions under 808 nm laser irradiation (1.0 W/cm²) from 0 to 5 min (n = 5); (C) Temperature change of the ZnO₂@Lip-ICG under repeated procedures (4 times) with 808 nm laser-on for 5 min and then laser-off versus time. (D) Cooling time versus negative natural logarithm of driving force temperature obtained from the cooling stage of (Fig. S5C). (E) Time-dependent ROS generation of free ICG, ICG@Lip and ZnO₂@Lip-ICG irradiated by 808 nm laser for 5 min presented by DPBF degradation. (F) Generation of singlet oxygen by measuring the fluorescence intensity changes of SOSG. The increase of SOSG fluorescence was a result of ¹O₂ generation.
