a Photodynamic Performance of GPRPP-Y8U@P (10 μg/mL GPRPP-Y8U@P + 5 μM SOSG) and irradiated (808 nm Laser, 1 W/cm2). SOSG was used to detect the singlet oxygen generation according to the protocol (excitation and emission wavelengths were 488 and 525 nm). b Pictures recorded the temperature change over time at the set concentration of 1 mg/mL. c The concentration-dependent PTT of GPRPP-Y8U@P. The temperature change with time under 0.6 w/cm2. d The power-dependent PTT of GPRPP-Y8U@P. The temperature change with time at the concentration of 1 mg/mL. e Particle size stability of GPRPP-Y8U@P after ten photothermal cycles. f Heating–cooling curve of GPRPP-Y8U@P
