Therapeutic effects of GP-PGA-Fe3O4-CDs@BPQDs in mice exposed to NIR after injection.
Notes: (A) Highest temperature within the tumor area recorded by an IR camera after 660 or 808 nm laser irradiation. (B) Thermography of tumor-bearing mice receiving photothermal treatment for different periods: a, 808 nm, 2.0 W/cm2, 5 min; b, 660 nm, 0.5 W/cm2, 10 min. (C) Weight-growth curves. Mice were measured every 2 days. (D) Tumor growth curves (n=5). Measurements taken after different treatments. (E) Mice with HeLa tumors after various treatments. (F) H&E staining of tumor sections collected from different treatment groups. Scale bar =50 μm.
Abbreviations: GP, genipin; PGA, polyglutamic acid; CDs, carbon dots; BPQDs, black phosphorus quantum dots; NIR, near-infrared; PTT, photothermal therapy; PDT, photodynamic therapy.
