Fabrication of alginate fibers using a microporous membrane based molding technique

Tubular structures made of alginate and similar hydrogels have been extensively investigated for drug delivery, tissue engineering and other biomedical applications. Alginate fibers are usually fabricated using complicated techniques such as coaxial flow extrusion or electro-spinning. This paper discusses the fabrication of hollow and solid alginate fibers using a simple membrane based molding technique. A hollow-fiber microfiltration membrane …
