Biomechanical and chemical characterization of elastic mussel threads from green mussels

Abstract

The byssal threads of the green mussel, Perna Viridis, are a critical part of the mussel’s survival. These elastomeric fibers exhibit intriguing mechanical properties and are capable of recovering mechanical performance when loaded beyond yield point. Furthermore, Perna Viridis is a very invasive species and causes numerous bio-fouling problems. The adhesive pads produced by the mussel are strong and durable, most importantly, it strives in water condition. Here, the structure-composition relationships that govern the distal mechanical properties of the threads are studied. In additional, adhesion of the plaque with different material is investigated. This study may aid in the development of bio-inspired engineering materials and antifouling coatings.
