DNA - Nanodevices

European Union

Status: finished project
Contract Number:
IST-2006- 029192
Starting date 
1 January 2006
Ending date 
31 August 2010

We propose the design, realization, and testing of DNA-based devices that can serve as building blocks for self- organized molecular nanoelectronics. This objective is stimulated by the encouraging results attained by our team over the last 3 years to produce novel DNA-based nanowires exhibiting conductivity signals.

The specific goals of the project are:

  1. Development of full control over the production process, specific modifications at desired locations, and the electrical properties of the conducting DNA-based nanowires (G4-DNA, M-DNA, DNA-polymer-hybrids);
  2. Realization of DNA-based molecular nanodevices with a non-linear electric response;
  3. Morphological, spectroscopic and electrical characterization of the above nanowires and nanodevices;
  4. Prediction and interpretation of the structural and electrical properties through complementary theoretical methods.

These objectives bear a huge promise in the context of device miniaturization: in fact, the limits towards scaling down electronic architectures and increasing circuit integration are strongly related to the ability to fabricate individual device components at the nanoscale (=10 nm and below). In particular, biological strategies may unravel new ways to assemble wires into devices and devices into functional networks, based on the spontaneous self-organization of intrinsically tiny components.
