Iron Oxide Nanoparticle-Based MRI Contrast Agents: Characterization and In Vivo Use

Iron oxide nanoparticles are one of the most important materials for magnetic resonance imaging. The possibility of multifunctionalization, lack of toxicity, and variety of compositions make them ideal for many applications. Furthermore, the new generation of nanoparticles for “positive” contrast will increase even more their utility, particularly in the clinic.
