Truly tiny factories

"These are DNA nanostructures that are self-assembled into discrete shapes. Our goal is to use these structures as bread boards on which to assemble carbon nanotubes, silicon nanowires, quantum dots," said Greg Wallraff, an IBM scientist and a lithography and materials expert working on the project. "What we are really making are tiny DNA circuit boards that will be used to assemble other components."

The work, which builds on the groundbreaking research on "DNA origami" conducted by California Institute of Technology's Paul Rothemund, is only in the preliminary stages. Nonetheless, a growing number of researchers believe that designer DNA could become the vehicle for turning the long-touted dream of "self-assembly" into reality.

In creating chip arrays, DNA assembly might work as follows: scientists would first create scaffolds of designer DNA manipulated into specific shapes. Rothemund has made DNA structures in the shapes of circles, stars, and happy faces.

Did I said before? I love origami! :D
