Magnetically Switchable Explosives Vapor Isolator(1001-687)

The proposed work details a molecular recognition based explosives pre-concentration and sampling system which can be coupled to a wide variety of current and future commercially available sensors. The system works by initially isolating and concentrating specific explosives from a sample stream through a novel, robust and tunable molecular recognition system. The concentrated molecules are released to the sensor in a preprogrammed manner through a novel desorption mechanism that minimally impacts the analyte of interest. The technology is easily adaptable to a broad range of explosive threat materials. Based on the success of our initial proof of concept work, we are proposing to extend the technology to build a working prototype.
