(a) UV-vis absorption spectra of SO9 in THF and SON9 in PBS. (b) Absorption intensity at 418 nm of SON9 (10−5 mol/L) mixed with 1,3-diphenylisobenzofuran (2 × 10−5 mol/L) in DCM over time at 660 nm laser irradiation. (c) Photothermal profiles of SON9 under different power density irradiation (660 nm). (d) Fluorescence images of SON9 in HeLa cells excited by 660 nm laser (left panel, fluorescence; middle panel, DAPI; right panel, merged images). (e) Fluorescence images of DCFH-DA in HeLa cells excited at 488 nm laser (left panel, DCF fluorescence; middle panel, DAPI; right panel, merged images). (f) The cell viability of HeLa cells after treatments with various concentrations of SON9 in different conditions. (g) Relationship between tumor volumes and time for various treatment groups.
