Some of the latest, groundbreaking research to come out of pnnl...a vapor detection technology.
It can detect vapor from explosives or drugs...faster and more efficiently than current technology.
The idea for something like this was sparked by 9/11...when the question of airport security became even more relevant.
That's the goal for these researchers -- to eventually get the technology used in airports.
