Fig. 2 — Magnetothermal performance and therapeutic efficacy of F/A@P with various components in vitro. (a) Magnetothermal curves of different volumes and mass fractions of Fe₃O₄ in F/A@P under AMF actuation and (b) the corresponding infrared thermal images. (c) Temperature curves of F/A@P over seven on-off cycles under AMF actuation. (d–e) Viability of 4T1 cells after different treatments assessed by CCK8 assay. (f) Live (green)/dead (red) fluorescence images of 4T1 cells after different treatments (scale bars: 50 μm). (g) FCM was used to determine the apoptosis level of 4T1 cells after various treatments. The data are shown as the mean ± SD, n = 3 per group; ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
