Abstract: Described herein are various three-dimensional fiber structures that have multiple polymer fiber layers with an active therapeutic agent entrained in the polymer fiber layers. Further described are methods for forming the three-dimensional fiber structures where the method includes centrifugal spinning of an emulsion containing polymer(s) and the active therapeutic agent(s).
