a Thermal images of PBS, ICG, and TPP-PPG@ICG during a 5-min irradiation (upper row) or a 10-min irradiation (bottom row). b Cell Counting Kit-8 (CCK-8)-based viability assay performed with doxorubicin-resistant MG63 cells (MG63/Dox cells) treated with ICG, TPP-PPG, PPG@ICG, or TPP-PPG@ICG, without laser irradiation. c Relative intracellular ATP concentrations in the MG63/Dox cells after incubation with PBS, TPP-PPG@ICG, ICG, TPP-PPG, or PPG@ICG for 6 h. Cells were treated with or without the NIR laser (808 nm, 0.6 W/cm2) for 5 min, and then their intracellular ATP concentrations were measured
