Abstract
In article number 1800051, Jason Warram, Yuping Bao, Eugenia Kharlampieva and co-workers demonstrate ultrasound-triggered drug release from MRI-visible polymeric microcapsules. Iron oxide nanoparticles are attached to the microcapsules which provide imaging contrast rivaling commercial contrast agents at a fraction of the metal concentration. The encapsulated drug is selectively released through ultrasound irradiation with minimized off-target uptake.
