Molecular dynamics (MD) is a method in which Newton s equations of motion are solved for a molecular system obeying a differentiable potential function. A few efforts at modeling proteins at interfaces using MD have appeared (183-187). Obviously, these studies provide dynamic as well as thermodynamic information on biomolecules at interfaces. Systems studied have included lysozyme and myoglobin on polyethylene glycol (183), cytochrome c on hydrophilic and hydrophobic self-assembled monolayers (184), leucine enkephalin near a crystalline polyethylene surface (185), thermal hysteresis proteins on ice (186), and lysozyme on polyvinylimidazole (187). 

It is important to examine the phenomenon of thermal hysteresis in some detail to appreciate how unusual the protein-based antifreezes...
