Abstract

Within the framework of a quantum mechanical model, the polarization component of the energy of cohesion of an ionized DNA molecule to the surface of a nanotube has been calculated. Neglecting the polarization of the DNA, and in the absence of external screening, the binding energy is ∼0.47 eV per elementary charge. The effective nanotube screening parameter is ∼2 and cannot be reduced to classical expressions for metallic and dielectric screening.
