Self-assembling nanotubes

The principle that makes DNA strands link together may someday be used to manufacture molecular wires and other components for use in electronic devices, according to Hicham Fenniri, an assistant professor of chemistry at Purdue Univ. To develop the self-assembling structures, Fenniri and his colleagues borrowed chemistry from DNA to create a series of molecules that are “programmed” to link in groups of six to form rosette-shaped rings, which then combine to form rod-like structures, or nanotubes.
