FeCo/graphitic-shell nanocrystals as advanced magnetic-resonance-imaging and near-infrared agents
&
Abstract
Nanocrystals with advanced magnetic or optical properties have been actively pursued for potential biological applications, including integrated imaging, diagnosis and therapy. Among various magnetic nanocrystals, FeCo has superior magnetic properties, but it has yet to be explored owing to the problems of easy oxidation and potential toxicity.
