Through biomineralization, nature is able to produce such engineering marvels as mother of pearl, or nacre, the inner lining of abalone shells renowned for both its iridescent beauty and amazing toughness. Key to biomineralization is the phenomenon known as “oriented attachment,” whereby adjacent nanoparticles connect with one another in a common crystallographic orientation. While the importance of oriented attachment to biomineral properties long has been recognized, the mechanism by which it occurs has remained a mystery. With a better understanding of oriented attachment it should be possible to synthesize new materials with remarkable structural properties.
