Control over aragonite crystal nucleation and growth : An in vitro study of biomineralization

Chemistry-A European Journal 4 (3) 389-396

Abstract :

Calcite and aragonite are the two most stable polymorphs of calcium carbonate. Even though they have very similar structures, many organisms are able to selectively deposit one poly morph and not the other. Recent in vitro studies have shown that one or more mollusk shell matrix macromolecules are capable of specific polymorph nucleation, provided they are in an appropriate microenvironment.([1]) In this study we examine aspects of the structure and function of some of the components of this beta-chitin-silk fibroin in vitro system.
