Optionally, the scaffold is a three-dimensional fiber scaffold including at least three systems of fibers, wherein two of the three fiber systems define the plurality of layers, wherein one of the at least three fiber systems interconnects the plurality of layers, and wherein the three dimensions of the scaffold define internal and superficial positions within the scaffold. The drug carrier design is versatile, such that drug release profiles can be customized for a given application.
