The "Metal Complexes and MRI" team, in collaboration with a Hungarian team, has developed a contrast agent based on an iron compound associated with a fluorinated ligand. This makes it possible to map oxidative stress in living tissue, a marker of numerous pathologies. This molecular detector, still at the pre-clinical stage, could considerably enrich tomorrow's medical imaging toolkit.
This major advance has been published in the journal JACS.
