Therapeutic efficacy of MFH in human lung cancer xenograft NUDE Balb/c mice exposed to an alternating magnetic field and iron(III) oxide nanoparticles doped with magnesium. A Animal weight gain in the experiment; B Kaplan–Meier survival analysis; C tumor volume assessed on the selected treatment day; D tumor mass and representative photographs of the tumors taken post-mortem from the mice on the day, which the mice were excluded from the experiment; E representative infrared images of temperature distribution in the tumor before MFH (left panel) and 15 min of MHF (right panel); F SAR values expressed as mean ± SD for xenografts (W·g⁻¹ of NPs)
