Abstract

Magnetic fluid hyperthermia (MFH) is a promising cancer therapy that relies on the heat dissipation of magnetic nanoparticles. To enhance the efficiency of MFH, materials with improved penetration and diffusion properties are required. Self-propelled nanomotors (NMs), driven by catalytic reactions, offer significant potential in this regard. Urease-powered nanomotors have demonstrated enhanced accumulation in tumors and improved therapeutic outcomes. This work presents a novel urease-powered magnetic nanomotor that functions as both a tracer for magnetic particle imaging (MPI) and a magnetic material for hyperthermia. The proposed nanomotor exhibits efficient diffusion and magnetic heating, making it an ideal candidate for MPI-assisted MFH therapy.
