In vivo antitumor performance evaluation of Bi2S3/Ti3C2-TPP. a HIF-1α expressions of tumors after different treatments. b Infrared thermography of U251 tumor-bearing mice after being injected with PBS (pH = 7.4, 10 mM) or Bi2S3/Ti3C2-TPP (20 mg kg-1). Time-dependent relative c body mass and d tumor dimension change plots from various groups. e The photos of U251 tumor-bearing mice from various groups during two weeks. f The representative photo of tumors dissected at 14 days post-injection. g Representative images of H&E (scale bar = 100 μm) and TUNEL (scale bar = 20 μm) stained slices of tumor tissues after different treatments
