  • Patent number: 10342881
    Abstract: Nanoparticles for use as magnetic resonance imaging contrast agents are described. The nanoparticles are made up of a polymeric support and a manganese-oxo or manganese-iron-oxo cluster having magnetic properties suitable of a contrast agent. The manganese-oxo clusters may be Mn-12 clusters, which have known characteristics of a single molecule magnet. The polymer support may form a core particle which is coated by the clusters, or the clusters may be dispersed within the polymeric agent.

  • Publication number: 20150338485
    Abstract: Disclosed herein is a novel MRI contrast agent. The MRI contrast agent is a metal particle having particular shape and size parameters that provides the metal particle with the ability to improve contrast by resisting transverse relaxivity saturation. The disclosed metal particle may be used in both medical and research diagnostic procedures, such as MRI, X-ray, and NMR. Also disclosed are compositions comprising the disclosed metal particle, and methods of using the metal particle. In particular disclosed embodiments, the metal particle is a barium ferrite particle.
