Figure 7

(A) (a) Thermal images during a 5-min irradiation (upper row) or a 10-min irradiation (bottom row). (b–d) Synergistic in vitro PT effects of TPP-PPG@ICG and laser irradiation on MG63/Dox cells. (b) CCK-8 viability assay at 24 h after laser irradiation. (c) CCK-8 viability assays with MG63/Dox cells exposed to TPP-PPG@ICG at 24 h post-laser irradiation at 808 nm, under conditions that inhibited PDT or PTT. (d) Images of calcein AM + PI co-stained cells. * p < 0.01. (B) In vivo synergistic PT for MG63/Dox tumor xenografts. (a) NIR fluorescence imaging of tumor xenografts and (c) the dissected organs from the tumor-bearing mice. (b) IR thermal imaging of tumor xenografts. (d) Photographs of representative tumors resected from different groups. Reproduced from ref. [343] with permission from BioMed Central. Copyright (2021) J Nanobiotechnol.
