Researchers Combine Weak Chemical Forces to Strengthen a Novel Imaging Technology

May 22, 2014 10:45 am | News | Comments

When Associate Professor of Chemical and Biomolecular Engineering Hyunjoon Kong, graduate student Cartney Smith, and colleagues set out to improve MR imaging (MRI), they turned current contrast agent technology on its head—or rather, they turned it inside out.  The new compound they designed in collaboration with Roger Adams Professor of Chemistry Steven C. Zimmerman is not only more effective, but also self-assembling.
