Nano-Scale Robot Arm Moves Atoms With 100% Accuracy

destinyland writes "A New York professor has built a two-armed nanorobotic device with the ability to place specific atoms and molecules where scientists want them. The nano-scopic device is just 150 x 50 x 8 nanometers in size — over a million could fit inside a single red blood cell. But because of its size, it's able to build nanoscale structures and machines — including a nanoscale walking biped and even sequence-dependent molecular switch arrays!"

    If it can move and place particles with 100% accuracy then at least at some point we know both where it is and how fast it's moving...

    does this mean someone can artificially alter their DNA using the nanobots?

  3. Exactly by dreamchaser · · Score: 4, Interesting

    Exactly. Moving individual atoms and placing them where we want them is about as fine grained as we can get before we run into the Uncertainty Principle.

  4. Misleading headline by flaming+error · · Score: 2, Interesting

    The article is about protein folding and manipulating DNA. It has nothing to do with a robot that picks up atoms and places them somewhere else.

  5. Re:"Success Rate" not "Accuracy" by m0nstr42 · · Score: 3, Interesting

    "100% Accuracy" implies a positional error of zero meters (to infinite decimal places), which is obviously not what they're talking about.

    I caught that, too. But really "percent" doesn't even make sense as a unit of accuracy, does it? Unless it's fractional, in which case I'd take it to mean that if you want to make a relative move of x, you'll get something in the range (0,2x) or maybe (0.5x, 1.5x)? I mean, on the nano scale that's still kind of remarkable, but as you've pointed out it's just not what they mean. /pedantic

    And when this technology matures it will be used not only to scrub CO2 but also in a eugenics program to scrub unwanted DNA sequences. If you think it can't happen you are very naive and put too much faith into humanity as a whole.

    Diamond manufacturing is already possible. The synthetic stuff is way cheaper than the stuff the cartels sell.

    Their reaction? Build better detector machines that can find the flaws present in a "natural" diamond vs. a synthetic one to tell whether it's worth anything. See http://en.wikipedia.org/wiki/Synthetic_diamond

  8. I Don't Believe It by Doc+Ruby · · Score: 2, Interesting

    I don't believe that there's such a thing as "100%" of anything happening at atomic scale. "100%" is what "99.9999999999999%" looks like when things are big enough that you have to drop the precision due to statistical balancing.
