Ultra-high rate of temperature increment from superparamagnetic nanoparticles for highly efficient hyperthermia.

ABSTRACT: The magneto-thermal effect, which represents the conversion of magnetostatic energy to heat from magnetic materials, has been spotlighted for potential therapeutic usage in hyperthermia treatments. However, the realization of its potential has been challenged owing to the limited heating from the magnetic nanoparticles. Here, we explored a new-concept of magneto-thermal modality marked by low-power-driven, fast resonant spin-excitation followed by consequent energy dissipation, which concept has yet to be realized for current hyperthermia applications. We investigated the effect of spin resonance-mediated heat dissipation using superparamagnetic Fe₃O₄ nanoparticles and achieved an extraordinary initial temperature increment rate of more than 150 K/s, which is a signif
