Duke University researchers have used self-assembling DNA molecules as molecular building blocks called "tiles" to construct protein-bearing scaffolds and metal wires at the billionths of a meter, or "nanoscale."
The achievements in nanoscale synthesis, which the five authors said could lead to programmable molecular scale sensors or electronic circuitry, were described in a paper in the Sept. 26, 2003, issue of the journal Science written by HaoYan, Thom LaBean, Gleb Finkelstein, Sung Ha Park and John Reif.
The Duke groups research was funded by the National Science Foundation, the Defense Advanced Research Project Agency, and an industrial partners arrangement with Taiko Denki Co., Ltd. Fashioning protein nanoscaffolds and silver nanowires may be only the beginning, because tiles of this form "can be easily programmed by varying the sticky ends to form more sophisticated arrays," the authors wrote.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
