AbstractABSTRACT: The use of taggants to mark and identify objects and materials is an emerging technology with many potential applications. One very important taggant application is the ability to remotely identify appropriately tagged materials and objects from airborne platforms. Biological materials, or bio-taggants, have the potential to effectively and selectively mark targets of high interest. Intelligent Optical Systems has demonstrated the ability to enhance the detectability of bio-taggants via a two pronged approach: using specialized, biocompatible quantum dots (QDs) as taggants, and using a specialized time-correlated photon counting system designed to sensitively detect QD fluorescence excited by eye safe laser radiation. Phase I work indicates that it is possible to detect QD labeled bio-taggants at altitudes of 100 m to 5 km. Phase II work will produce and demonstrate a field deployable prototype capable of deployment on an air platform. A partnership will be established with a military prime contractor to make the taggant detection available for procurement. BENEFIT: The proposed quantum dot labeled bio-taggant methodology and time correlation enhancement will result in an entirely new class of military, forensic and law enforcement tools. Remote detection has applications in monitoring terrorist activities, illegal drug activity, and even the illegal dumping of toxic materials. In addition, as costs come down, it may be possible to employ this technology for industrial and agricultural activities, such as wide field studies of fertilizer application effectiveness and the use of genetically modified organisms.
