A new method for loading iron inside nanoparticles creates MRI contrast agents that work better than the mainstay gadolinium chelates, which face increased scrutiny due to potential safety concerns, researchers say.
“The possibility of eliminating gadolinium exposure and getting a two-fold improvement in T1 MRI contrast performance is going to intrigue radiologists,” says lead researcher Naomi Halas, professor of electrical and computer engineering and of chemistry, bioengineering, physics and astronomy, and materials science and nanoengineering at Rice University. “When they hear we’ve done this with iron I expect they will be very surprised.”
