ASU researchers 'wire' DNA to identify mutations

ill a subject of speculation. "One idea is that there is a tunneling process," said Tao.

The DNA has properties which make the electrons easier to tunnel through, just like lowering a hill for a marathon runner.

"The other may be a charge-hopping phenomenon, where the electrons get trapped in the DNA and then hop from the electrode to the DNA to the second electrode."

The next goal of the research is to make the measurement steps easier and faster through automation, which will allow many different DNA sequences to be analyzed at once.
