The combination of magnetic properties and bio-compatibility makes these microspheres a promising tool in oncology.
Mechanisms of Action
The mechanisms of action of magnetic microspheres in cancer treatment primarily involve their role in drug delivery and hyperthermia therapy. One of the pioneering strategies is the use of magnetic targeting. In this approach, the microspheres are injected into the bloodstream and guided to the tumor site using an externally applied magnetic field. This targeted delivery system aims to concentrate therapeutic agents at the tumor site while reducing systemic exposure and potential side effects.
Once the magnetic microspheres reach the tumor tissue, they can release their payload, which often consists of chemotherapeutic drugs.
