23 Jul Nervous tissue engineering fibrous membrane and preparation method
Abstract
The invention discloses a nervous tissue engineering fibrous membrane and a preparation method. The method comprises the following steps of: dissolving a high molecular material into water or an organic solvent to prepare electrostatic spinning solution; injecting the high molecular solution into an injector; performing electro-spinning to form nanofibers, which are arranged tidily, to prepare a high molecular fibrous membrane; and immersing the high molecular fibrous membrane into pyrrole aqueous solution to form core-sheath fibers. In the preparation method of the nervous tissue engineering fibrous membrane provided by the invention, the fibrous membrane is constituted by conductive core-shell nanofibers; the core is high molecule which has excellent material biocompatibility; the nanofibers are arranged tidily by controlling the preparation conditions; the shell-layer material is polypyrrole; the biocompatibility is good; the prepared core-sheath fiber can provide a unique platform to grow and extend neurites; and the process is simple, easy to operate and low in cost and has broad application prospect in the field of nervous tissue engineering.
