(a) Photodegradation curves of 1,3-diphenylisobenzofuran (DPBF) in the presence of BDP-CR under 671 nm irradiation. (b) DPBF absorbance change at 415 nm after the MB, CR, BDP, and BDP-CR were treated with 671 nm irradiation. Temperature change of (c) BDP-CR and (e) BDP in the PBS buffer solutions (0.01 M PBS, PBS/DMSO = 2:1 v/v, pH = 7.4) at various concentrations (0, 5, 10, 20, and 40 μM) under 100 mW/cm2 irradiation (671 nm). (d) Photothermal imaging of part c. (f) Photothermal heating curves for the change of temperature with time when BDP-CR (20 μM) was irradiated by 671 nm light at different power densities (0, 25, 50, 100, and 200 mW/cm2). (g) Absorption spectra of BDP-CR pre- and post-671 nm light irradiation (200 mW/cm2, 10 min). Insets are photographs of BDP-CR dispersion before (left) and after (right) light irradiation. (h) Absorption spectra of ICG solutions pre- and post-808 nm light irradiation (200 mW/cm2, 10 min). Insets are photographs of ICG solution before (left) and after (right) light irradiation.
