Definition of Magnetic-targeted carrier

Magnetic-targeted carrier: A tiny bead made from particles of iron and carbon that can be attached to an drug. A magnet applied from outside the body then can direct the drug, for example, to the site of a tumor. This can keep a larger dose of the drug at the tumor site for a longer period of time, and help protect healthy tissue from the side effects of chemotherapy.
