Preparation and biological application of sericin protein based hydrogel
Hydrogel is a kind of polymer material with three-dimensional network structure.Because its structure and function are similar to those of biological tissues,it has been widely used in biomedicine and other fields.Seri-cin is a potential hydrogel substrate because of its abundant resources,various biological activities and excellent physical and chemical properties.Sericin based hydrogel is a kind of gel material containing sericin protein with three-dimensional network structure.In this paper,the structural composition and characteristics of sericin protein were introduced firstly,then the extraction methods and gel mechanism of sericin protein were expounded,and the preparation of pure sericin protein hydrogel and sericin protein composite hydrogel were summarized.Finally,the biological application of sericin protein based hydrogel was briefly analyzed.
