Recently a number of novel drug delivery systems have emerged to minimize drug dose and loss to prevent harmful side effects, excess bioavailability, and controlled drug delivery. Microspheres constitute an important part of this particulate drug delivery by virtue of its small size and efficient carrier characteristics. Magnetic microspheres has been alternatively traditional method for delivery of drug to the targeted site by reducing the amount of free drugs circulating the whole body by reducing excess dose dumping for limiting toxicity and for reducing the side effects of the drug. The magnetic microspheres are delivered using an external magnetic energy to help and reach the carrier,to the targeted site. The review gives an overview of the size,properties, mechanism, benefits, drawbacks, different preparations and applications of magnetic microspheres.

Magnetic microspheres, magnetic targeting, magnetic properties, biomedical applications.
