NACRE. “The organic matrix of nacre: a peptide CAP-l from a crayfish with a chitin binding motif, a phosphoserin unit for promoting the initial formation of amorphous CaC03 (ACC) and an acidic binding domain for CaCOl led to a mesoClystal film after nucleation ofACC, crystallization and nanoparticle alignment on a film composed of parallel a-chitin microfibrils. Here, calcite nanoparticles were aligned along the chitin fibrils.”
