Gone fishing : Unidirectionally oriented CaCO 3 crystalline films have been prepared on chitin matrices in the presence of calcification‐associated peptide (CAP‐1), which was isolated from the exoskeleton of the red swamp crayfish. The interactions of CAP‐1 with the matrix and the acidic nature of the peptide lead to a filmlike assembly of CaCO 3 nanocrystals through transformation of amorphous calcium carbonate (see picture).
