Magnetic-driven drug delivery technology is a method by which magnetic drug carriers in the body are manipulated by external magnetic fields to reach the target area. Magnetic microspheres have gained wide attention because of their many varied applications, ranging from administering the medicine directly to pinpointing the exact drug location in a blood vessel for proper monitoring, to detecting leakages and assisting the entire diagnostic process. These magnetic particles can also be used as magnetic beads that are capable of releasing drugs into a vesicle through mutual attraction and repulsion between magnetic poles.
The most commonly used magnetic drug delivery technologies are based on the concept of magnetic targeting. This concept is based on the fact that different magnetic particles have their own distinctive magnetic properties. Therefore, if we can exploit these properties to produce a magnetic field that is strong enough to induce a chemical reaction, then this will definitely yield a therapeutic effect. The most commonly used magnetic targeting agent is called HCT (High Curved Ceramic Capsules). This type of magnetic drug delivery system uses a highly effective ceramic plate, composed of iron oxide, to transfer the medicine into a patient's body.
