Promising approaches in using magnetic nanoparticles in oncology

The development of new and effective drug delivery systems for cancer treatment represents one of the significant challenges facing biomedical technology in the last decade. Among the different methods of drug delivery, magnetic drug targeting, by enabling specific delivery of chemotherapeutic agents through the use of magnetic nanoparticles and magnetic field gradient, could be a promising approach. Recently, magnetic nanoparticles have attracted additional attention because of their potential as contrast agents for magnetic resonance imaging and heat mediators for cancer therapy. This review summarizes these approaches in the use of magnetic nanoparticles in biomedical applications and novel methods for their optimization.
