Flourescence optical micrograph of YOYO labelled lamba DNA, on an amino modified oxidised silicon wafer substrate, after having been stretched using molecular combing.

Research has been undertaken to establish whether DNA can effectively transport electrons. This ability could play an important role in acting as a repair mechanism to the DNA helix, should it suffer radiation damage. Furthermore, recent results have shown that DNA can carry an electrical current on a par with conducting polymers and the best of semiconductors. This suggests that DNA could be used as a component in the manufacture of micro-electronic devices.
