Abstract

Breaking of the symmetry of a single-wall carbon nanotube in the field of a helical wrap of ionized single-stranded DNA is investigated. For a non-chiral tube, the helical perturbation generates "natural" optical activity in the DNA-nanotube complex. The one-electron absorption spectrum for light polarized across the tube is sensitive to the band structure modulation due to the wrapping. Lifting of optical selection rules results in new optical transitions and circular dichroism of the complex. These optical effects are predicted to serve as qualitative tools to directly identify the DNA wrapping.
