Killing Cancer Cells With Magnetic Nanoparticles

South Korean University researchers have demonstrated a method of using nanoparticles activated by a magnetic field to precisely target cancer cells, and effectively have them commit suicide. This is without the use of anything other that the nanoparticles and a magnetic field.
The magnetic switch uses zinc-doped iron oxide magnetic nanoparticles (Zn0.4Fe2.6O4), combined with a targeting antibody for death receptor 4 (DR4, a protein on the surface of certain cells — in this case. of colon cancer cells).
See? Don't know why I didn't think of it.
