DNA, the blueprint of life, has taken centre stage in biological research during the past few decades. DNA plays an important role in molecular biology as the carrier of genetic information in all living species. Bio-physicists and chemists have become increasingly interested in the electronic properties of the “molecule of life”; DNA. Experiments are now starting to provide the first clues about the mechanisms that underlie charge transport in DNA. They sparked the creation of whole new industries based on this knowledge and on the various biotools and technologies that have subsequently developed. Biologically, the well-known function of DNA is to code for functional proteins that are the expressed form of hereditary, genetic information. But in the past few years, the discovery that DNA can conduct an electrical current has made it an interesting molecule for other roles that nature did not intend for this molecule. DNA could be useful in nanotechnology for the design of electronic circuits, which could help to overcome the limitations that classical silicon-based electronics is facing in the coming years.
