Abstract:
Wound healing is tightly regulated in both space and time. To mimic this behavior, we designed magnetically-responsive, fiber-hydrogel composites. When covalently crosslinked hydrogels were combined with layer-by-layer stacking, we demonstrated precise spatial control over fiber orientation. For temporal control, we used non-covalently crosslinked hydrogels to enable in situ fiber alignment.
