Hierarchical Structure and Fabrication of Functionally Graded Biointerfaces in the Mussel Byssus
Advanced Materials Interfaces, EarlyView.The byssus is a fibrous protein‐based holdfast consisting of mechanically distinct interfaces, which mussels use to anchor their soft living tissue to hard seashore surfaces. Here, multiscale methodologies were used to elucidate the compositional and structural features underlying these functionally graded interfaces and how they are fabricated through
