Biological materials have evolved over millions of years. In the structural studies of biological materials, it is observed that at the mesoscale (~100 nm to few μm), the mineral crystals are preferentially aligned along the length of the organic-phase polypeptide molecules in a hierarchical (e.g., staggered or Bouligand pattern) arrangement. Multicomponent hierarchical structure of biomaterials results in the organic–inorganic interfaces involved at different length scales, i.e., between the basic components at the nanoscale, between the mineralized fibrils at the microscale, and between the layers of the multilayered structures at micro- or macroscale. Interfaces control biological reactions, provide unique organic microenvironments that can enhance specific affinities, provide self-assembly in the interface plane that can be used to orient and space molecules with precision, etc. This collection provides recent research work done in the area of interface mechanics of collagen- and chitin-based biomaterials along with various techniques that can be used to understand the mechanics of biological systems and materials.
