Engineers pattern graphene using DNA molecules

Scientists are also interested in graphene rings because they can be used as quantum interference transistors, a novel type of transistor created when electrons flow around a circle. This type of behaviour has only recently been observed, and this fabrication technique could allow scientists to create many rings so they can study this phenomenon more thoroughly.

In the longer term, the DNA nanostructure fabrication strategy could help researchers design and build electronic circuits made of graphene. This has been difficult so far because it's challenging to place tiny carbon structures, such as nanotubes and nanowires, onto a graphene sheet. However, using the metallized DNA masks to arrange structures on a sheet of graphene could make the process much easier.

The new approach is "conceptually novel," says Robert Haddon, a professor of chemical and environmental engineering at the University of California at Riverside, who was not part of the research team. "The work shows the potential of self-assembled metallized DNA nanoarchitectures as lithographic masks for wafer-scale patterning of graphene-based electronic circuit elements. I believe that this approach will stimulate further research on the application of nanopatterning techniques in graphene-based nanoelectronics."
