Abstract

Ascidians as a typical marine fouling organisms can rapidly attach to the surface of underwater substrate temporarily by means of papillae during larvae, and subsequently developed successively to reach permanent adhesion via ampulla, adhesive projection and stolon. The special adhesive organs and associated complex mechanisms make it difficult to develop antifouling strategies against these species. However, it also brings new ideas for the development of novel hydrogels or effective antifouling surfaces. Here, we review the mechanisms of biological adhesion at larval and adult stages in ascidians, and summarize the existing research on antifouling and biomimetics. The research progresses are suggested including adhesive organs, identification and analysis of adhesive proteins, designing specific materials for preventing adhesion of ascidians, and biomimetic research of ascidians based on the molecular level to provide theoretical reference for further studies on the adhesion mechanism of marine organisms and the development of antifouling strategies and bionic materials.
