The goal of UCTED is to prototype our patented sensory materials into portable devices that are suited for infield explosives detection. The sensory materials are composed of well-defined nanofibers fabricated from different building-block molecules. As covered in our five IPs, the nanofibers are highly efficient for vapor detection of explosives, via optoelectronic modulation upon interaction with the targeted explosives. Upon integration into a small unit, the entangled nanofibers form a mesh-like, highly porous film, providing maximal sampling of explosives, enabling expedient vapor detection with unprecedented efficiency (down to ppt range). This is superior to the common solid film-based sensory materials, for which the sampling of trace analysts remains difficult due to the limited surface area. Compared to conventional electronic detection systems like those based on MS or IMS, the nanofibers represent a class of simple, small and adaptable detection system.
