We are all aware that DNA is the genetic material of living organisms. However, the same properties that make it such a good molecule for that purpose can be exploited to form structures on the nanometer scale. This effort utilizes synthetic DNA molecules with sequences designed to produce branched, rather than linear species. These branched species have been organized into objects, lattices, and nanomechanical devices. This research is aimed at control over the structure of matter: We are seeking to self-assemble macromolecular crystals that can act as hosts for macromolecular guests and enable crystallographic studies, as well as the organizing of nanoelectronic components.
