In vitro magneto-inductive heating of Fe₃O₄/Cur@ALG NPs induces the death of sarcoma 180 cells. (A) The temperature (°C) values reached after stimulating the Fe₃O₄/Cur@ALG NPs with an alternative magnetic field (AMF). (B) Images of sarcoma 180 cells stained with Trypan blue after incubation with 2000 µg/mL Fe₃O₄/Cur@ALG NPs and AMF. (C) Percentages of cell death (%) after 30 min of AMF irradiation. (D) Cell death (%) at different time points after finishing the 30- and 45-min AMF protocols after treatment with 2000 µg/mL Fe₃O₄. Data are presented as the mean ± SD of triplicate experiments. * p ˂ 0.05; ** p < 0.01; *** p < 0.001.
