Photothermal efficacy analysis of the NCs.
(a) Heating profile of different concentrations (25, 50, 100, 200 and 400 ppm) of PEGylated NCs (suspended in water) upon NIR irradiation. (b) Plot of difference in temperature attained upon 600 sec (10 min) NIR irradiation of different concentrations of NCs. (c) The heating and cooling profile of 100 ppm NCs in terms of difference in temperature. (d) Plot of cooling period (after 600 s) versus negative natural logarithm of driving force temperature. Time constant (τs) for heat transfer is determined to be 157.89 s. (e,f) Temperature rise from 24.5 °C to 94 °C within 10 sec of NIR irradiation observed with non-PEGylated bare NCs solution. (g–j) Temperature rise from 26.8 °C to 59 °C was recorded post 3 min of NIR irradiation with PEGylated NCs solution.
