ABSTRACT
The charge-transport properties of the DNA double helix have intrigued chemists, physicists, and biologists essentially since the structural features of this molecule were revealed over 40 years ago [1]. The stack of aromatic heterocycles within the double helix allows the readout of genomic information through the display of functional groups within the grooves of this molecule. The striking similarity of the π-stacked array of DNA bases to π-stacked solid-state conductors has prompted the suggestion that DNA might efficiently facilitate charge transport [2]. This intriguing proposal, along with relevance of charge migration in DNA to biological function and biosensing, has prompted the examination of this phenomenon from many different scientific perspectives.
