Blood Coagulation-Promoting Silk Fibroin-Polypeptide Electrospun Membrane and Preparation Method Thereof

Abstract

The present invention discloses a blood coagulation-promoting silk fibroin-polypeptide electrospun membrane and a preparation method thereof. The electrospun membrane is made by using silkworm silk fibroin as a carrier and adding the polypeptide GPRPPSEHLQIT. It is mainly used for promoting blood coagulation, and is a blood coagulation material that can targetedly bind to human fibrinogen. The preparation method includes the steps of dissolving, filtering, dialyzing, concentrating and freeze-drying silkworm cocoons after degumming to obtain silk fibroin freeze-dried powder. The polypeptide used in the present invention is a polypeptide obtained by self-screening. Compared with other polypeptides, it can specifically targetedly bind to human fibrinogen.
