Nanoparticles make better MRI images
Manganese oxide nanoparticles have been used as contrast agent for magnetic resonance imaging (MRI), allowing researchers to see inside living brains in the same detail as dissected tissue under a microscope.
The team, led by Taeghwan Hyeon of Seoul National University in South Korea, say that this is the first biocompatible nanoparticle MRI contrast agent - it is also effective for liver, kidney and spinal imaging.
