  Attraction between the polycyclic aromatic surface elements of carbon
nanotubes (CNT) and the aromatic nucleotides of deoxyribonucleic acid (DNA)
leads to reversible adsorption (physisorption) between the two, a phenomenon
related to hybridization. We propose a Hamiltonian formulation for the zipper
model that accounts for the DNA-CNT interactions and allows for the processing
of experimental data, which has awaited an available theory for a decade.
