A school of Rhode Island professor is rolling out a sensor that detects the kind of explosive used in the particular Paris bombings, to try and stop future attacks.


Professor Otto Gregory compares his sensor to your dog's nose, the gold standard in explosives detection. It "sniffs" the air for vapors emitted from explosives.

Inside his laboratory, Gregory is evaluating the way well his sensor registers triacetone triperoxide. The Paris attackers packed TATP to their suicide vests and wielded strike rifles, killing 130 people today Nov. 13.

TATP was also used in the 2005 London bombings, which usually killed 52 commuters, as well as by Richard Reid, who tried unsuccessfully to help detonate a bomb in his shoe throughout a trans-Atlantic flight in 2001.

TATP is not hard to make, and the materials are readily available in pharmacies and equipment stores, experts say. Even small quantities causes large explosions. The OUGHOUT. S. Department of Homeland Stability began funding Gregory's process a center for explosives study in 2008.

His sensor is designed to continuously monitor an community, unlike a quick swab on the hand or of luggage at the airport to screen regarding particulates from explosives. It does not need training or breaks or cracks, as bomb-sniffing dogs complete.

"Think of it for electronic dog's nose that is going to run 24/7, " claimed Gregory, a chemical anthropological professor.

Homeland Security created a new center of excellence regarding explosives experts to collaborate and enhance the nation's response to risks, called the ALERT, or maybe Awareness and Localization involving Explosives-Related Threats, Center.

Gregory's function is fairly mature, and also a commercial partner will probably desire to invest, said ALERT Heart Director Michael Silevitch.

"You can't have a very dog everywhere, " Silevitch claimed. "The more we could screen vulnerable targets, the better off we're going that they are. "

I. The filter paper contains small amounts on the explosive TATP and emits a vapor employed in testing and developing detectors for a good the explosive. TATP was included in the Paris attacks.

The sensor measures this energy that's released like a molecule as an explosive reduces. Nanowires in the sensor act as a catalyst to cause that decomposition therefore , the explosive can be found. The system also procedures the electrical properties with the catalyst as it interacts considering the explosive vapor, as an extra check.

It detects both equally nitrogen-based and peroxide-based explosives, Gregory explained. He envisions it being affixed from a Jetway or an entrance into a nightclub, stadium, subway or other public space, inducing an alarm if explosives are generally detected.
The first prototype would likely cost roughly $1, 000 for you to $2, 000, Gregory explained. He's working on the hand-held version he shows would cost several number of dollars, and he's talking with companies enthusiastic about licensing it.

A Homeland Security spokeswoman said she couldn't discuss the project until it can be complete.
