One step toward the nanofactory

This could be a big step in solid-state memory, and alternative CPU architectures, but the most promising applications can be molecular mechanics.

These approaches to DNA computing can already have the theoretical potential to make very simple and small scale molecular manufacturing, using the so called DNA Robots.
Manufacturing nanoscale objects with an already working method was something I believed would take 5 to 10 years to achieve. I guess that future is today!

(but still don't wait for a Star-trek based replicator in the near future)

Nanotech systems based on DNA may be on the verge of becoming very large and complex, if not immediately useful to medicine or manufacturing. Researchers have combined simple strands of DNA into the most elaborate logic circuits yet, with potential for even more growth, the creators say. Another group has turned DNA chains into a rudimentary robotic system, namely a grid containing dozens of flipperlike arms.

I recently came across your blog and have been reading along. I thought I would leave my first comment. I don't know what to say except that I have enjoyed reading. Nice blog. I will keep visiting this blog very often.
