Swapping the chemical groups that originally coat iron oxide nanoparticles and making the particles soluble in biological solvents shows great promise for medical applications, such as drug delivery and contrast agents, according to a recent publication by University of Alabama engineers and scientists highlighted in Nature magazine. According to an article published in the Aug. 4 issue of Nature, “the tiny particles of iron oxide can have their surface chemistry manipulated to make them soluble in water and so more useful in medical application.”
