They Walk. They Work. New DNA Robots Strut Their Tiny Stuff.

I came across this article today while getting ready for work.  The artist’s rendition of the ‘bots was worth an immediate posting alone!

These experimental devices, described in the journal Nature, are advances in DNA nanotechnology, in which bioengineers are using the molecules of the genetic code as nuts, bolts, girders and other building materials, on a scale measured in billionths of a meter. The effort, which combines synthetic chemistry, enzymology, structural nanotechnology and computer science, takes advantage of the unique physical properties of DNA molecules to assemble shapes according to predictable chemical rules.

We are that much closer to seeing this put into real life conditions.  Another decade, two or even three perhaps?

One can only dream…
