23 Jul Fibroin protein fiber scaffold and preparation method thereof
Abstract
The invention relates to a fibroin protein fiber scaffold and a preparation method thereof, after degumming of silk, the silk is soaked in an acid solution for dispersion to obtain a silk fiber dispersion solution; the silk fiber dispersion solution is injected into a mold for freezing to obtain a silk fiber frozen body; the silk fiber frozen body is immersed in an organic solvent to remove formic acid, and soaked and washed with deionized water to obtain a wet-state fibroin protein fiber scaffold; the-state fibroin protein fiber scaffold is coldly treated to obtain a frozen body, and the frozen body is frozen and dried to obtain the fibroin protein fiber scaffold. The internal structure of the fibroin protein fiber scaffold mainly comprises fiber, and the fibroin protein fiber scaffold has high porosity, high penetration rate and excellent mechanical properties, is very conducive to nutrient transport, cell migration and tissue growth, and is an ideal tissue engineering scaffold.
