Nanoconfinement concept improves safety of diagnostic
contrast agent

More than seven years ago Albert J. Sinusas, MD, a
professor of medicine, radiology, and biomedical engineering, was
working with a team of engineers for development of an imageable
polymer for prevention of adverse remodeling after a heart attack
when they inadvertently discovered that when iodine, a contrast
agent used for X-ray imaging, is packed in a nanoparticle there is
greater absorption of X-rays potentially improving
visibility.
