The 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.

Abstract
The 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.
