Photothermal properties of PDA@SCM NPs. (A) UV–vis absorbance spectra of SCM vesicles, PDA NPs and PDA@SCMs NPs. (B) Photothermal heating curves of PDA NPs and PDA@SCMs NPs in aqueous medium at different concentrations irradiated with an 808-nm laser (0.6 W/cm2, 5 min). (C) Thermal stability of PDA NPs and PDA@SCMs NPs under NIR-laser irradiation over five laser on/off cycles. ***p < 0.001.
