Abstract:

Preparation, mechanism of gelatin, modification treatment, mechanical properties and rapid prototyping of the silk fibroin hydrogel, and research of 3D bioprinted silk fibroin hydrogels in our group are introduced in this paper. The aim is to systematically analyze the advantages and disadvantages of the various preparations and the purpose of the modification of silk fibroin hydrogels, and explain the mechanism of gelatin and rapid prototyping of silk fibroin hydrogels. The paper provides a reference for preparation of the high quality silk fibroin hydrogels and the further development of industrialized production of silk fibroin hydrogel.
