Abstract

Several fields are interested in the mechanism by which organisms control crystallisation at ambient temperatures. Here, the authors evaluate the mechanism of magnesium rich nanoprecipitate layer formation in the calcite crystals of the brittle star, via the decomposition of the amorphous precursor.
