Super-Sensitive Spray-On Explosive Detector

esocid writes "US scientists have designed a new spray-on explosive detector sensitive enough to detect just a billionth of a gram of (nitrogen-containing) explosive. After treatment, the explosive glows blue under UV light, making the detector perfect for use in the field. The silafluorene-fluorene copolymer can detect explosives at much lower levels than existing systems because it detects particles instead of explosive vapors, and is able to show the difference between nitrate esters (trinitroglycerin) and nitroaromatic explosives (TNT). The team is currently working on a similar system to detect peroxide-based explosives and say they hope to be able to investigate perchlorates and organic nitrates, too."

    I thought cocaine could only blow your mind. It's explosive too?

    A spray-on explosives detector already exists. Here's a picture of it in action in a field situation where explosives may have been present.

    That one has a few negative side effects, though... Maybe this new one improves on them? That'd probably be helpful in airports.

    The article isn't terribly specific about which nitrogen compounds react to the spray, only providing a couple of examples. If I worked in my garden 5 days before a flight, am I going to get Tazed by TSA because I didn't eliminate every last speck of fertilizer from my clothes? There, fixed your question for ya. You're welcome! There, fixed your welcome for you. No, no, it was my pleasure.

    In a month anyone NOT detectable by this absurd theater will be assumed to be a no-good-nik because they DON'T set it off.
