In vivo IPT–BT synergistic therapy of SW1990 pancreatic tumor–bearing mice. a) Thermographs of mice administrated with PBS (100 µL) or HGNs (250 µg mL⁻¹, 100 µL) exposed to NIR irradiation (2.0 W cm⁻², 5 min). b) Bioluminescence images of tumor‐bearing mice post various treatments. c) Relative tumor volume in the group of control, BT, HGNs + BT, HGNs + IPTT, and HGNs + IPT–BT groups on day 16 post treatment. Insets: corresponding digital pictures of tumor post treatments. Scale bars are 1 cm. d) H&E stained images of major organs after therapy. Scale bars are 100 µm.
