Due to the potential applications in nano-electronics and molecular electronics, the electronic transport properties of DNA molecule materials have attracted considerable attention of scientists. However, a consensus on the electronic transport properties of DNA molecules has not yet been established. In this paper, the theory and experiment research developments in electronic transport of DNA molecules are outlined. Direct charge transport measurements indicate that the DNA molecules may be insulators, semiconductors, or conductors. Theoretically, both first-principles calculations and model based Hamiltonians are extensively adopted to describe DNA molecules and to interpret such diversity of experimental results.
