Polaronic charge transport mechanism in DNA
For the detailed understanding of the conduction mechanism in DNA we use models
based on the concept of polaron and breather solutions. We describe how charge
transport relies on the coupling of the charge carrying unit to the vibrational modes
of DNA allowing for the formation of polaron-like localised states. The mobility of
these localised states is discussed particularly in the presence of parametrical and
structural disorder inherent to biomolecules. It is demonstrated that long-range coherent
charge transport along the DNA structure is supported by mobile polaron
and breather solutions suggesting that DNA seems suitable for the design of functional
nanostructures as ingredients in molecular nanoelectronic devices
