The recent Yemeni bomb threat has only highlighted the need for quick, accurate ways of detecting explosives. With their excellent sense of smell and the ability to discern individual scents, even when they’re combined or masked by other odors, this task is usually given to man’s best friend. But training these animals can be expensive and good sniffer dogs can be hard to find. Scientists have now developed an electronic sensor they say is more sensitive and more reliable at detecting explosives than any sniffer dog.
[…]
The device is made from an array of silicon nanowires, coated with a compound that binds to explosives to form a nanotransistor. To enhance the device’s sensitivity, the scientists developed each one with 200 individual sensors that work together to detect different kinds of explosives with what the scientists say is an unprecedented degree of reliability, efficiency and speed

Good… now maybe we can dump the x-ray scanners and intrusive pat-downs.

    Nope…. they can’t sniff a box cutter.

    Hell, even a ballpoint pen can be a weapon.

  3. soundwash says:

    oh please…

    -it took to the year 2010 for these asshats to come out with this?

    (someone please expose the 9/11 fraud once and for all so we can end finally end all this BS terror absurdity)

    Get rid of scanner and pat downs ? No way !!! The TSA (Titty Squeezing Agency) will just use the nanowire sensor on a dildo to JAM UP YOUR A$$ES !!!

  5. chuck says:

    Can they program it to do false positive results?
    The best part of using sniffer dogs (for the police) is that all they have to do is make the dog bark and then they can strip search and anal-probe you.

  6. Improbus says:

    The job of the TSA is to intimidate the public. What they do is theater. I am just glad I don’t have to fly anywhere.

    Better living through electronics.

    I like the “friendliness” of getting a doggie to sniff my crotch.

    I don’t like the way they make those wretching sounds after. (Some people use “jock” deodorant, I use pepper spray. 🙂

    Where am I going to get my jollies if they get rid of the crotch sniffing doggies?

    um.. Crotch sniffing cats?

    Don’t be silly. Where’s the intimidation in that? I’d be happy if it let me keep my shoes on!

  10. RSweeney says:

    We have heard this kind of stuff before.

    I believe it when it’s in common use and working well.

    Bees are better and cheaper than either one of them. Seriously.

  12. bobbo, not a tech guy says:

    “The device is made from an array of silicon nanowires, coated with a compound that binds to explosives to form a nanotransistor.” /// I wonder what is the “heart” of this device: silicon, nano tech, or the compound=or the functionality/requirement of all three?

    Silicon=just the substrate, nano just the size, so its the compound? Those compounds been around and known for a long time but needed the nano to be able to make a portable detector? And you can’t get nano without the silicone==meaning its small because it can be photo produced??

    The future is so bright, I gotta wear shades.

    OK,
    SEND MY DOG BACK…

    Ok,
    does this work in a vehicle traveling 40mph down the road, or does my target need to be STANDING for 5 minutes..
    They have been working on this since about 2003, it was shown on PBS…IT SUCKED and wasnt FAST.

  14. sargasso_c says:

    I for one welcome a complementary grope.

  15. Improbus says:

    @sargasso_c

    Are you saying that if it weren’t for TSA’s complementary grope you would get no love at all? You must work in IT.

  16. Cap'nKangaroo says:

    Have they determined what innocuous products will give false positives? Trailers loaded with Kitty litter are always setting off those radiation detectors at the US border. Drivers who get these loads take it as a given that they will have to go thru at least the vehicle X-ray building if not worse (unloading the trailer to check pallet by pallet).

  17. sargasso_c says:

    #15. Improbus I think they’re becoming suspicious.

  18. ECA says:

    I have to say something here.
    A SEALED BOMB, gives off NO FUMES/SCENTS/ANYTHING until it goes boom.. And it isnt hard to do.

  19. ± says:

    #7 …. You spray pepper spray in your crotch before flying? I like the concept, but don’t understand the physics. Help me out?

  20. Zybch says:

    #18 Actually its incredibly hard to achieve a sealed bomb, especially one you can shove up your man-pussy or hide in your underpants.

    [Man-pussy?! – ed.]

  21. martron3000 says:

    Oh great! Now we’re going to have homeless sniffer dogs, out of work, wandering the streets, begging for “Kibble & Bits”!

  22. ECA says:

    #20..
    iTS CALLED SARAN WRAP..

    Make bomb in 1 room..walk to sealed room,
    Place
    And someone ELSE NOT NEAR the materials WRAP…

    you would need to be ON TOP of it to smell it..
