Photothermal effect of nGO-PEG and nrGO-PEG. (A) Temperature curves versus time during irradiation with 808 nm laser (0.6 W/cm2) for vials containing water, nGO-PEG (3 μg/mL), and various concentrations of nrGO-PEG, respectively. (B) Thermal images of vials with water, nGO-PEG, and nrGO-PEG (3 μg/mL) after irradiation by 808 nm laser (0.6 W/cm2) for 8 min.
