Innovative Nanoparticle Purification System Uses Magnetic Fields

Caption

A team of Penn State University scientists has invented a new system that uses magnetism to purify hybrid nanoparticles. The system holds the promise of helping to improve drug-delivery systems, drug-targeting technologies, medical-imaging technologies, and electronic information-storage devices. This 'nano-flower' is an extremely small particle made up of a gold core and iron oxide 'petals.' Structures like this one are of great interest in biomedicine for drug delivery and for use as an MRI contrast agent.
