Abstract

The protective characteristics of silkworm cocoons are the result of thousands of years of evolution. In this study, we attempted to combine the cocoon’s protective characteristics with the function of human skin to explore the possibility of using silkworm cocoons in the field of artificial skin application. We retained the natural structure of the cocoon shells and softened it by a degumming process. This process was performed so that the mechanical and permeation properties of the cocoon material meet the criteria of artificial skin with respect to tension and suturing; the cocoon material was also found to have strong antibacterial activity and cell compatibility. These properties of the cocoon suggest that it has a high potential to be used as an artificial skin. Overall, we expect the silkworm cocoon to be a type of biological material with extensive possibilities of application as artificial skin.
