FutureWatch: A New TSCM Detection Tool is in Development...

The developers just don't know it yet.
It's an Electronic Dog Nose (EDN).

New sensors developed by Otto Gregory at the University of Rhode Island, and chemical engineering doctoral student Peter Ricci, are so powerful that they can detect threats at the molecular level, whether it's explosive materials, particles from a potentially deadly virus or illegal drugs entering the country.

"This is potentially life-saving technology," said Gregory. "We have detected things at the part-per-quadrillion level. That's really single molecule detection."

Because Gregory's sensors are so small and so powerful, there is a wide range of applications. more

Kevin's analysis...
Specially trained dogs have been used to sniff out covert electronic items, like cell phones in prisons, for quite a while now. The secret to detection is the device's electronic circuit boards. They contain these compounds: triphenylphosphine oxide (TPPO) and hydroxycyclohexyl phenyl ketone (HPK). This second compound is also found on CDs, DVDs, Blu-Rays, the old tech floppy disks.

FutureWatch: Technical Surveillance Countermeasures (TSCM) professionals have many types of technologies at their disposal for detecting illegal electronic surveillance devices. To name a few... Non-Linear Junction Detection, Infrared Thermography, and Radio-frequency Spectrum Analysis. We are now well on our way to adding EDN to our kit.
