Abstract

See full text

A system for forming twisted or aligned electrospun fibers has been developed. The collector for the electrospun fibers is capable of rotation. In some instances, fibers are formed between two collectors, at least one of which rotates to twist the fibers into a multifilament bundle with increased strength. In a second embodiment, a cylindrical collector rotates, and charged polymer jet uniformly coats the surface of the collector. When a drum collector rotates at a high speed, electrospun fibers align and form an array. Optionally, different active agents can be included in the electrospinning solutions to form fiber constructs with different strengths and controlled release profiles, providing a reproducible method to generate complexed structures based on electrospun fibers and controlled drug delivery profiles.
