Ferro-Sponges for Drug and Cell Delivery
Xuanhe Zhao, Jaeyun Kim, and David Mooney



A ferrogel was created with controlled structures on multiple length scales. Application of a magnetic field induces large strain (>80%) with fast response times (<1s) to lead to burst release of drugs and cells embedded within the gel.
