Silk fibroin is regarded as a biomaterial for a long time. The fantastic biocompatibility of silk fibroin makes it a hot spot in the biomedical area and many researches has chosen it as a basic material to create new biomaterials. However, it has a long biodegradation period in body. Gamma ray is a method to accelerate degradation of other material in some experiments. This research combines silk fibroin with gamma ray and tries to figure out whether gamma ray can make the biodegradation of silk fibroin shorten. In this article, we give various doses of gamma ray to silk fibroin films and take some measurements about the mechanical and molecular structure of post-radiated silk fibroin, thus to choose an appropriate dose for the future research.
