  • animated SEM is too awesome..

  • i find this difficult to masturbate to

  • this was really interesting, but the music was super annoying, and the video quality made it hard to read. So A+ on the research. D- on the video.

  • waiting for the first misanthrope that figures how to make a self replicating nanovirus to consume all of earth and maybe more. can we stop it?

  • @wtfronsson

    We would

  • Fantastic!

  • Have they ever droped one .. oops!

  • Nano Thermite has conclusively been found at the WTC site. All the dust samples show the stuff. watch?v=4RNyaoYR3y0 shows one of many interviews of those scientists who have used deep scanning tunneling electron microscopes to find the structure of the red/gray particles..... ae911truth also has many interviews on Nano Thermite. Legally provable. It's in every dust sample tested

  • anytime!!

  • a few hundred micrometers long. We made them down to 30 micrometers long, with a 400 nm wide gap. The size of a salmonella bacteria is about 400 nm, and the width of a human hair is 30-50 micrometer.

    (micron = 0.000001 meter)

  • how small would that holder thing be

  • I am glad u like it :-)

  • Nanomasturbation

  • ...i get these really long nose hairs......

  • Have you tried brazilian wax? It hurts, but its cheaper

  • haha thanks for making me laugh, that was a win comment.

  • thanks for the laugh

  • I really wonder, if this technology will enable science to better undertand and/or control the growth or CNTs.

    I mean, like shaping a substrate with ion beams to encourage more perfect CNTs to grow longer, or shaping nano particles with a special surface that will allow better growth.

    Or possibly some sort of continous-growth-precedure to produce infinately long fibers.

  • From the university of Chapel Hill's chemistry program to being a former sit-in student of the M.I.T. program, I find this "next generation nanomanipulation project" to be amazing. High REsolution is incredible and speaks in volumes about the project. yes this is an awesome display

  • Font is hard to read and too small!

  • Thanks, we know. We wont make that mistake again :)

  • @NanoClips Itwas still really awesome and I must say an impressive demonstration :D

  • LOL, it got magnetized to the pole. SNAP! It teleported =Þ.

  • fractals

  • It goes NOWHERE! lest it grows hair.

  • next time post it in HD

    you can barely read whats written in ur video

  • nanotechnology = future

  • Well the interesting thing about nanotechnology in the future is that it wont be called nanotechnology. As it enters our daily lives (which is already doing to a great extend,, like the nanopatterning on dvds, harddisks and blurays) nobody will be interested in the "nano" story - as long as the product is cheap and works well

  • @sajnajmr That was actually the Title of My nanotech presentation the other week lol

  • Comment removed

  • the music is "gaeshue", the track is called control49, you can find it on myspace

  • thanks, i prefer the mix that was used in your video =P

  • the nanotubes are grown: a carbon-containing gas (e.g methane) is heated up, which cracks the molecules. Carbon likes to sit on Nickel, so if we make Ni nanoparticles, the carbon assemble there in form of nanotubes, growing up like bamboo....

  • they're grown!?

  • the grippers are made out of silicon :)

  • what music was used ?

  • Wow, that was an excellent read. Thank you!!

  • Wow, that was an excellent read. Thank you!!

  • Both the top-down and bottom-up approach have much merit to them, and their individual pros and cons. What is the point of rebuking one and adulating the other?

  • What with the the nanoscale fontsize?

    Otherwise, great video, cool background music, what is that?

  • this would b good 4 my pubic lice, get some bigger type nano eyes

  • this is merely to create tools for the next level of micronization as well as to begin to create the engines that are driven by the smaller mechanisms and chemical catalyts

  • VERY IMPRESSIVE!!! I hope someday nanotechnology will cure my blind eye..

  • Why not just genetically engineer bacteria to manufacture the grippers? Or even just modify organelles and proteins from bacteria to do the things we want them to? This seems like a cave man's approach to nanotechnology to me. We already understand the theory behind chemistry, it behaves in exactly the way we predict it to, so why are we still trying to manipulate the world with these proxy representations of our hands?

  • Well... "just modify"... thats the point. Maybe in 50 years, it will be possible to do that, and then I'll be 91. I cannot wait so long - we are indeed at the cavemans level right now. You are just suggesting the caveman (me) to skip the boring "handcraft tool, develop wheel etc" and go to robots. Have patience! Molecular nanotechnology in is very far from being useful on the scale shown in the film.

  • I disagree, I seem to remember reading about nano legs that can walk on a nano ladder made out of simple genetic material. Pieces of normal nucleotides and amino acids, things that show up in normal living things, that were exploited to do something we wanted it to do. I fail to see this anthropomorphization of things at the nano scale as being the foundation of true nano tech.

  • using genetic material to harvest a carbon nanofiber like this one is like cutting a tree with a nailfile. "Molecular tweezers will soon build thousands of nanocircuits" sells newspapers but have so far failed to do the slightest hint of good. Genetics is more relevant for nanomedicine. I am not claming our work to be "true nanotech" (which i find is a meaningless term). The hypothesis is that mechanical hands could be of use on the nanoscale, like they certainly are on the macroscale.

  • I think your hypothesis has only been validated on a very superficial level. We already know that the graspers (which are psychologically just extensions of our clunky hands) will not behave in the same intuitive manner since we are starting to come face to face with the strangeness of quantum physics. We simply must re-evaluate this philosophy of Top-Down theorizing. We already know enough to start from bottom-up.

  • ... we know enough to start, sure! But if you know enough to start, you also know that it will long time before bottom-up can process larger complex structures. Assembly line industry depends entirely on robots to do the work. Are these people stupid? Do you use your hands? *We* are perhaps superficial stoneage researchers, but we have made this tool and it picks and places nanostructures. It is not "philosophy" or "theorising" it is "reality".

    Reality is great when you want something done :-)

  • ... I am not defending this research compared to bottom up research - just attempting to motivate why we are interested in it, and possibilities we see. Bottom up assembly is something althogether different, and I have the greatest respect for the researchers who fight to puth things together with chemistry - it is very important research, and holds much promise for the future. Speaking of which (the future) I should be more cautious discussing. It is something *everyone* knows very little about

  • I can tell you right now, the chemistry approach is going to be easier, cheaper, and more theoretical. Your top down nano grasper approach is going to be less efficient, more expensive, and extremely limited. The only practical application I could imagine before the chemistry approach replaces it is examining forensic evidence for crime scenes.

  • Robots are doing human scale work. We can't manipulate chunks of metal and plastic in an elemental or predictable manner through nudging the way we can manipulate proteins and individual atoms. The only reason I use my hands is BECAUSE i can't manipulate individual atoms. If I could manipulate matter at the atomic level, I'd never need my hands again.

  • Dear DeimosSaturn. "The only reason I use my hands is because i cant manipulate atoms"... are you sure? The only reason? How about typing on computers, cooking and about 10000 other things you use your hands for? You are strong in the faith, and your arguments are beyond my powers of reason. Thank you for sharing your points of view and for your enthusiasm; i will get back to assembling nanostructures and developing novel tools to do so - stay tuned, and keep thinking about what nano can do :)

  • YES. I AM SURE. Keyboards are designed for human hands. If I could manipulate matter at the atomic level I could simply manipulate the CPU directly. Nothing I say is in faith...you just haven't tried to meet me half way. Our hands and any extension of them are just that. Big clumsy paws and modified spears or clubs. Go ahead and continue this vein of research...it will be quashed by the true nano-sciences in the recent future.

  • I have no problem with something better replacing what we are doing now.. Its called progress and thats what we live for. In my view there are much, much more obvious uses of molecular nanotechnology than mechanical manipulation. The thing is: it wont be around the next 3 decades (replacing grippers I mean), and we cant wait that long. Grippers are not competing with large-scale fabrication - it is a serial tool, not a parallel. With a gripper you can do flexible work, build 1 prototype.

  • DeimosSaturn, it seems to me that you are arguing on matters of which you understand very little. Chemists can do impressive work with their bottom-up methods, but mixing stuff in reagent tubes will *never* be able to do what the nano gripper just did; moving a nanowire from a substrate to a analysing grid, which is something you have to be able to do in order to analyse it.

  • A DNA molecule can be adapted to do the work of a nano gripper. I know PRECISELY what I'm talking about.

  • Then perhaps you wouldn't mind showing us an in situ electron microscopy movie of that. I'll even settle for a few article references.

  • Nice videos.

    Would you make a video about the whole machine while its working?

  • ok - we have done that... will be up soon :)

  • no, the film was sped up - the factor varies, but its something like a factor of five. The actual manipulation can be done with the speed in the film (but there was no reason), but the long transport from the nanotube surface to the TEM grid (the destination structure) cannot be done quite as fast.

  • Is this really captured in real-time? Amazing... I had no idea the sate of the art was this far advanced. =o
