Anisotropic dynamics of ice growth promotion and its self-oscillation induced by the interfacial adsorption of biological macro molecules

Experimental and theoretical studies of antifreeze proteins, which have the special function to prevent the freezing of living organisms under the subzero environment, were carried out. Direct evidence for the relation between the adsorption of proteins on the ice interfaces and the prohibition of crystal growth was first demonstrated directly, and it was made clear that the protein molecule adsorption proceeded in two stages depending on the conformation change of protein molecules. This adsorption mode was completely new and called as "two-step reversible adsorption". This adsorption model also explained the growth promotion of basal planes of ice and the self oscillations of growth rates.
