Magnetic Nanocrystals Carry Tumor-Killing Drugs

Imagine using a focused magnetic field to concentrate anticancer drugs in and around tumors, and then turning off the magnetic field so that the drugs then leave the body. That possiblity may become a reality as a result of work showing that magnetic nanocrystalline iron-nickel alloys can effectively carry and release anticancer agents. The results of these experiments appear in the journal Acta Biomaterialia.
