In vitro and in vivo photothermal performance. (A) Fluorescence images of KYSE150 cells stained with Calcine AM/PI in the copresence of the PVP and BW nanosheets, respectively, combined with 808 nm laser irradiation. (B) Images of tumor sites injected intratumorally with BW nanosheets with 808 nm excitation, before and after PTT (photothermal therapy). (C) Tumor growth curves of mice treated with different groups: PBS, PVP, and BW during 16 days. (D) Body weight variation of mice corresponding to various groups. (E) Ultimate tumor weight after different treatments in 16 days.
