Photothermal and photodynamic performances of the sPDMA@ICG NP solution. a Temperature changes of the sPDMA@ICG NPs solutions upon laser irradiation at different ICG concentrations. b Fluorescence intensities of SOSG (λex = 504 nm, λem = 525 nm) in the solutions of PBS, sPDMA, free ICG and sPDMA@ICG NPs upon laser irradiation (+ L). Here, the ICG concentrations for free ICG and sPDMA@ICG NPs were 10 μg/mL. In the above experiments, the laser irradiation was carried at 808 nm at 2 W/cm2 for 10 min
