The Nanotech Nose: Towards A Smaller Future 90

Posted by michael from the bigger-and-better dept.
Farrax writes "One of the first steps to nanotechnology, either strong or weak, is the ability to even talk about materials on this scale with precision. Thursday, with the successful test of a nano-tech "nose," that step was achieved: weight fluctuations of 5.5 femtograms were detected on a bar of gold. The dream of nano-technology moves forward: maybe we'll see it by 2020 after all."

    i just can't wait till everything is super dense and super fast. One of the things i'd like to see is how they stabalize stuff like that. stuff so small i'd imagine it can get very weak easy to break. then again it can't build up very much momentum to cause breaking away from something that's holding it.

      Actually, on this scale things are very, very mechanically strong, depending for their strength on atomic bonding.

      Think of trying to break a particle of talcum powder, rather than a tiny little teacup.

    I imagined from the moment I heard of nanotech, that we could have devices implanted in ourselves that, when we're in the sun, could bring chlorophyll to the surface of our skins and create food from it. That way we can all use up CO2 from the atmosphere to offset the CO2 emissions of industry, and help industry along all the more!

    We get the benefits of industry, with free food, and a way to combat one of the current downfalls of industry!

    i wonder if things will eventually reach a point where it's no longer beneficial to get any smaller?

    for instance, mobile phones nowadays are a great improvement from a 1-foot long cellphone our grandparents used, but if things get too small for human-beings to use it properly, then we won't use it.

    so with all these nano techonologies going on, even if we can build all the components for a mobile phone so small, don't we still need something reasonable sized to use it?

      You're forgetting that it's a lot easier to put a small thing *INTO* a larger container, rather than trying to squeeze something big into a smaller space.

      It's true that you'll never see a standard cell phone the size of a postage stamp, but if you can make a single chip with all the functionality of a cell phone, you can then build it into any form factor you choose -- why not build an entire phone INSIDE an ear bud (Uhura-style)? Suddenly you no longer need to have any big bulky parts extending all the way to your mouth.

      And if all the functionality of a cell phone fits into something the size of your fingernail, that makes it easier to incorporate it into a more complex device, like a PDA or wristwatch or whatever.

      Functionally, the latest-and-greatest Ford Compensator is no different than a Geo Miniscule with a lot of empty space added to it.

      Similarly, there's nothing stopping you from integrating a PDA-on-a-chip into a 17" tablet format to get a considerable savings in power consumption, etc.

      Just because it's small doesn't mean it can't still be used effectively.[*]
