Abstract:The teeth of limpets, consisting of orderly aligned hard goethite (iron oxyhydroxides) nanocrystals and flexible chitin microfibers, are one of the hardest and stiffest biomaterials found in nature. However, the replication of their composition and ordered microstructures to artificial biomimetic materials remains a challenge. Here, we fabricated large-sized limpet tooth analogues with hierarchically ordered structures by applying long-range orientational control to the short-scale self-assembly of hybrid coll… Show more
