Magnetic nanoparticles can 'burn' cancer cells: Magnetic hyperthermia is still a highly experimental cancer treatment, but new research shows that the therapy is tunable

Among emerging cancer therapies, one approach is based on hyperthermia. In a new study, researchers show that tumor cells' specific absorption rate of destructive heat depends on the diameter of the nanoparticles and composition of the magnetic material used to deliver the heat to the tumor.
