  "main_findings": "Nude mice with head and neck tumors treated with cetuximab-coated superparamagnetic iron oxide nanoparticles followed by a weak external alternating magnetic field (4 Hz) showed a superior cell death effect over time compared with pure antibody. Tumor-site necrosis was detected by MR imaging. Thermal camera imaging of head and neck squamous cell carcinoma cultures suggested cell death occurred via a purely mechanical (non-thermal) mechanism.",
