(A) Absorption spectra of Gd-TMV-PDA at different concentrations before (solid line) and after (dashed line) irradiation (808 nm laser, 1 W/cm2). Inset shows a picture of the 200 μg/mL Gd-TMV-PDA solution. (B) Thermal images of different concentrations (50–667 μg/mL) of Gd-TMV-PDA irradiated for different durations (808 nm laser, 1 W/cm2) recorded with an IR camera, and (C) the corresponding temperature change profiles. (D) Temperature profiles and thermal images of 667 μg/mL Gd-TMV-PDA solution irradiated with an 808-nm laser at different power densities (0.4–1 W/cm2). (E) Temperature variations of a Gd-TMV-PDA over eight cycles of heating and natural cooling. (F) Confocal fluorescence images of live (calcein-AM: green)/dead (propidium iodide: red) PC-3 cells treated with Gd-TMV-PDA before and after irradiation (808 nm laser, 1 W/cm2) for different durations (1–5 min). Scale bar = 50 μm.
