Regenerated silk fibers extruded from fibroin solutions are highly lustrous and have uniform diameters and circular cross-sections. They are stronger, more extensible, and tougher than natural silkworm silk. These fibers can be spun under clean, sterile, and carefully regulated conditions, and may permit direct incorporation of drugs for controlled release, being suitable for biomedical applications.
