Abstract. A numerical study is presented to investigate the role of solitons in the elec- tronic states of double-stranded DNA (dsDNA) molecule in the metal/DNA/metal sys- tem. Based on tight-binding Hamiltonian model and within the framework of a generalized Green s function technique, we consider a ladder model for poly(dG)-poly(dC) DNA mole- cule containing M cells with four sites (two base pair sites and two backbone sites) in each cell. In the presence of a sublattice of solitons, our results show that the homogeneous soliton distributions induce the electronic states in the band gap of DNA molecule. In addition, the room temperature current{voltage characteristic of the system shows a linear and ohmic-like behaviou
