MD of a DNA and a surface?



 Dear netters, I am trying to make an MD simulation of a single stranded DNA
 on a surface. Does anyone know of computational models for calculating
 interaction energies between the planar surface of a solid of a known crystal
 structure and an adsorbed protein ??
 I would deeply appreciate any response with information about: models,
 refreances, literature, source codes (and other sources) and programs.
