Nanotechnology is applied in a variety of biomedical and bioengineering proceedings. Magnetic nanoparticles of different sizes with tailored surface chemistry are used in vitro in a routine setting for cell separation and in vivo as magnetic resonance imaging contrast agents, hyperthermia and drug delivery. A potential benefit of using these particles is the use of external magnetic fields to focus the particles to a particular site in the body and to hold them until the therapy is complete. All these efforts point to an aim in which drugs are only delivered to specific sites and at therapeutic levels.
