23 Jul Biodegradable tissue-engineering fiber
Abstract
The invention relates to the field of biomedical engineering materials and in particular relates to a biodegradable tissue-engineering fiber. The biodegradable tissue-engineering fiber is made from natural silk as principal raw material. The natural silk is degummed, dissolved and purified to form a silk fibroin solution. And the silk fibroin solution is processed by wet spinning method which controls that the degree of crystallization of silk fibroin is less than 40%, to produce the biodegradable fiber used for tissue-engineering scaffolds. The material is innoxious and harmless, has good biocompatibility, is hardly soluble in water, has strength, elongation, elasticity and other physical properties, and can be used as the material of artificial skin, artificial tendons, artificial cartilages, artificial dura maters and other tissue-engineering scaffolds or used as the surgical repair material.
