Producing method of synthetic collagen nano-fiber

Abstract

With respect to synthetic collagen that has so far been difficult to be nano-fiberized, a method for producing uniform and long fibrous nano-fibers containing a synthetic collagen is described. The nano-fibers contain a polypeptide having a peptide fragment represented by Formula (1): -(Pro-Y-Gly)n  (1), wherein Y represents hydroxyproline or proline, and n is an integar ranging from 5 to 9000. The producing method includes a step of preparing a spinning solution containing the polypeptide and a polymer, and a step of spinning with an electrospinning method using the spinning solution.
