Photothermal property evaluation of SF/CM-PDA scaffolds. UV–vis–NIR spectra of SF/CM and SF/CM-PDA scaffolds (a). Temperature changes in the SF/CM-PDA scaffolds with 808 nm laser irradiation at different laser power densities (0.8, 1.0, 1.3, and 1.5 W/cm2) (b) and PDA solution (c) for 6 min. Infrared thermal images of the SF/CM-PDA suspension exposed to NIR irradiation (808 nm, 1.3 W/cm2) for 6 min (d). Temperature change increase in 2 mg/mL PDA solution-functionalized SF/CM-PDA scaffolds over five irradiation cycles (808 nm, 1.3 W/cm2, and 1200 s intervals) (e). Fitting curves between the time and logarithm of the temperature during the cooling process (f).
