In vivo photodynamic therapy (PDT) by gelatin–Ce6 in tumor-bearing mice. a Tumor images after intravenous injection of saline, free Ce6, gelatin–Ce6-2, or gelatin–Ce6-8 (2.5 mg/kg of Ce6) and laser irradiation (658 nm, 0.3 W, 200 J). b Tumor growth after PDT by saline, free Ce6, gelatin–Ce6-2, and gelatin–Ce6-8 (2.5 mg/kg of Ce6) (n = 4). *p < 0.01. c Body weight change of the mice after PDT (n = 4). d Images of H&E-stained tumor tissues 14 days post-treatment. Scale bar represents 100 μm. #Means early sacrifice due to large tumor size
