The influence of biomolecules on crystallization in living systems leads to dramatic control over crystal shapes, growth rates and properties. AFM studies of crystal growth in which both synthetic and naturally occurring biomolecules are introduced during growth, in combination with computational modeling of modifier-crystal interactions, have led to new insights into mechanisms of biomolecule-driven growth modification. Amongst the important factors that have emerged are the stereochemical relationship between modifier and step edge, the strength of binding to terrace and step edge sites, and the effect of biomolecules on crystal and solute solvation state. Here we illustrate these factors using examples from the calcite and calcium oxalate monohydrate systems, in which carboxyl-rich biomolecules are used to influence growth.
