DNA molecular wires could be incorporated into electronic devices in the future
US researchers have shown for the first time that a 34nm long DNA strand can be used as a molecular wire to conduct electricity. In the future, DNA could be used in nanoscale electronic computers, they say.
Consumer electronic devices are becoming smaller and smaller which means molecular wires that conduct electricity at the molecular level are of great interest to researchers. The helical structure of DNA is very similar to the pi stacked solids used in electronics as electrons are delocalised around the strands and could be used to transport charge.
