Targeted Chemotherapy Delivery
Several types of focused drug-delivery modalities are possible using nanomagnetic particles. In a direct delivery method, anticancer drugs are chemically attached to nanoparticles, in addition to the antibodies. These chemotherapeutic agents would then be absorbed by the cell after the nanoparticle attaches. In a more sophisticated thermal delivery method, the chemotherapy agent can be encased in a specially designed polymer shell around the magnetic core. After the nanoparticle is bound to its target cell, external magnetic fields can be used to slightly heat the polymer to allow for drug release.
