Design by DNA

DNA molecules provide the architecture for all living things. New York University chemist Ned Seeman thinks they could also be a perfect assembly platform for the smallest computing devices ever built.

So is nanomanufacturing imminent?
We are probably not going to be using this approach to knit customized sweaters. DNA is expensive stuff; for now, at least, you wouldn't want to use it for large-scale anything. But 3-D configurations of atoms, or molecules, or nanoparticles - that has to have value, in terms of making things no one has been able to make before.
