MICOT Corporation In written testimony,8 MICOT Corporation proposed using a taggant consisting of randomly shaped particles made from a chemically stable thermoplastic resin, encoded with a custom numerical code combination of 10 or more colored layers. MICOT_ particles are detectable with an ultraviolet lamp or magnet and come in sizes from 15 to 1,000 microns (or higher)

Missouri Scientific Corporation In written testimony,l2 Missouri Scientific Corporation proposed using inorganic glass microspheres called Identispheres_ to facilitate the preemptive detection of explosives and easy taggant recovery and identification. The available variables of Identispheres_, such as particle size and fluorescent properties, were reported to provide a large number of combinations with which to uniquely identify a product.

These luminescent chemical additives were reported to be water soluble, nontoxic, and biodegradable. Science Applications International Corporation In written testimony,~4 Science Applications International Corporation proposed a detonator detection system based on multiphoton detection, a technique based on measurement of radioisotopic tracers whose decay is accompanied by the emission of multiple high-energy photons.

They are reportedly chemically inert, have an infinite shelf life, and are nonhazardous, impossible to circumvent, and inexpensive. University of Strathclyde, Scotland In written testimony,20 the University of Strathclyde, Scotland, proposed selective tagging of explosives using surface enhanced resonance reman scattering as a detection technique.
