a) Photothermal heating curves of BP@PEG NSs (70 ppm), Ce6 (9 ppm), BP@PEG/Ce6 NSs (BP@PEG, 70 ppm), and PBS solutions under 660 nm laser irradiation (0.65 W cm−2, 10 min). b) Time‐dependent absorption spectra of BP@PEG/Ce6 NSs solution under 660 nm laser irradiation (0.45 W cm−2). c) Relative viabilities of HeLa cells after treated with BP@PEG NSs, Ce6, and BP@PEG/Ce6 NSs at different concentrations of BP@PEG NSs (1, 2.5, 5, 10, 25, and 50 ppm) or Ce6 (0.13, 0.325, 0.65, 1.3, 3.25, and 6.5 ppm) with irradiation (660 nm, 0.65 W cm−2, 10 min). d) Tumor growth curves of tumor‐bearing nude mice with various treatments (n = 4, mean ± SD, *P < 0.01). e) Photographs of tumors collected from the sacrificed mice. f) H&E stained histological images of major organs after 14 days treatment (scale bar, 100 µm).
