Coupling DNA nano-breadboards to solid state conductors

DNA is not only a most extraordinary information storage medium: the programmable pairing of DNA single strands into precisely engineered, connecting double helices make it an extremely appealing material for assemblage of nanoscale architectures. This is the basis of DNA nanotechnology, and designing almost any structure made of DNA at the nanometer scale, decorating it with a variety of functional molecules, and accomplishing it by virtually inexpensive self-assembly, is already a reality in many research laboratories in the world. But can we extend the range of applications of this technology by coupling DNA grafted molecular electronic nano circuitry to solid state devices, and interface molecular smart functions to our senses? This challenging research is addressed by a collaborative research among ENEA, the Universities of Roma 'Tor Vergata' and 'Aarhus', and the CNMS of the Oak Ridge National Laboratory. The first results obtained by our consortium pave the way to the technological ability to interface and use completely self-assembled, DNA-based electronic nano-breadboards, endowed with ultra-high-density functional organic components
