The European project IST-2001-38951 "DNA-based molecular nanowires" started in January 2003 having the Molecular Computing group as a project node.

An international consortium of 7 universities and research centers are seeking an alternative to silicon-based microelectronics in using molecules of DNA, which could enable a reduction in size of the current systems by a thousand times. The University of Regensburg is participating in this project through the research group led by Dr. Gianaurelio Cuniberti of the Physics Department.
The really innovative nature of this project lies, on the one hand, in the use of all the recognition and self-assembly potential of biological systems, more specifically, using derivatives of DNA such as G4-DNA, M-DNA and PC-DNA with a greater electronic potential than DNA itself (which is by itself an insulator). On the other, it lies in carrying out studies in surface chemistry combined with scanning probe microscopy (SPM) and spectroscopy, the measurement of electrical transport, sophisticated nano-manufacture and theoretical studies of the computational simulation of the stability and properties of synthesized devices and/or motivating new structures that might have a greater potential. In this way the manner of designing nano-wires using these molecular derivatives is being developed. As is the way of controlling the interaction between the molecular electrode and the molecular substrate, seeking a deep understanding of the energy conduction mechanisms of these nano-wires and being able to produce models of nanomolecular devices based on these DNA derivatives.
