Photothermal heating curves of MPSNs aqueous solution (A) with different concentrations and (B) with different laser power densities. C Photothermal effect of the MPSNs solution (100 μg/mL) under irradiation of 808 nm laser (0.6 W/cm2) for 600 s min and left to cool down then, inset: Linear time data versus negative natural logarithm of the temperature driving force which is obtained from the cooling stage. D Temperature variations of the MPSNs under irradiation (808 nm, 0.6 W/cm2) for five light on/off cycles (600 s of irradiation for each cycle). E Photothermal images of MPSNs in solution under laser irradiation
