Fig. 4. The photothermal effect of (A) CuS-apoferritin and (B) CuS-apoferritin-MBA aqueous solutions irradiated by 808 nm laser light (0.8 W cm−2). The infrared thermal images of CuS-apoferritin and CuS-apoferritin-MBA aqueous solution after 808 nm laser light irradiated for different times (1, 3, 5, and 8 min) at different concentrations (C) 100 μg mL−1 and (D) 200 μg mL−1.
