Abstract
The presently disclosed subject matter provides a scalable and electrostretching approach for generating microfibers exhibiting uniaxial alignment from polymer solutions. Such microfibers can be generated from a variety of natural polymers or synthetic polymers. The hydrogel microfibers can be used for controlled release of bioactive agents. The internal uniaxial alignment exhibited by the presently disclosed fibers provides improved mechanical properties to microfibers, contact guidance cues and induces alignment for cells seeded on or within the microfibers.
