Submission + - Heating nanoparticles to kill tumor cells (sciencedaily.com)

jouassou writes: Magnetic fluid hyperthermia (MFH) is a promising new cancer treatment that essentially "fries" cells inside tumors. The procedure has been used successfully in prostate, liver, and breast tumors. Magnetic nanoparticles (each billionths of a meter in size) are injected into the body intravenously and diffuse selectively into cancerous tissues. Add a high-frequency magnetic field, and the particles heat up, raising the temperature of the tumor cells.
