  Long range charge transfer experiments in DNA oligomers and the subsequently
measured -- and very diverse -- transport response of DNA wires in solid state
experiments exemplifies the need for a thorough theoretical understanding of
charge migration in DNA-based natural and artificial materials. Here we present
a review of tight-binding models for DNA conduction which have the intrinsic
merit of containing more structural information than plain rate-equation models
while still retaining sufficient detail of the electronic properties. This
allows for simulations of transport properties to be more manageable with
respect to density functional theory methods or correlated first principle
algorithms.
