Figure 3: Plots of the temperature increase (ΔT) versus the irradiation time of an NIR laser obtained from (A) DMEM (0.1 mL) and (B) RPMI medium (0.1 mL) containing different concentrations of Fe3O4 MNPs and from (C) DMEM (0.1 mL) and (D) RPMI medium (0.1 mL) containing different concentrations of Glu-Fe3O4 MNPs. The temperature of the samples was maintained at 37oC in the beginning of the laser irradiation.
