effect of an electric field on the adsorption of oligopeptides and
DNA on a ferromagnetic substrate magnetized perpendicular to the surface
was investigated. The direction of the magnetic moment of the substrate
defines different adsorption rates for different enantiomers, and
the direction of the electric field, perpendicular to the surface,
defines different adsorption rates depending on the direction of the
dipole moment of the adsorbed molecules.
