MRI flatlander

Researchers at Stony Brook University New York have developed a highly effective and potentially safer nanoparticle-based MRI (magnetic resonance imaging) contrast agent using the carbon allotrope graphene. There have been health concerns aired recently about the conventional gadolinium-based contrast agents used in medical imaging. Now, Balaji Sitharaman and colleagues have demonstrated how a graphene-based contrast agent could work at much lower dosages than standard contrast agents. The team also points out that their putative replacement is also a lot less expensive.
