Innovative Sampler and Terahertz Spectroscopy as CBR Sensor

The objective of this proposal is to evaluate the efficacy of the novel combination of microstructured aerosol and gas collector and terahertz (THz) spectroscopy techniques to non-invasively collect and detect hazardous chemical vapors, biologicalpathogens and toxins, and nuclear materials of interest. MicroEnergy Technologies and the University of Wisconsin-Madison have substantial experience in every aspect of the novel combination of filtration and detection, including air sampling for CBRagents, surface sampling, and optical spectroscopy. We will integrate a miniaturized terahertz spectroscopy system with microstructures to develop a state-of-the-art high signal-to-noise ratio chemical, biological, and nuclear agent detection system.During Phase I of this project, we will perform the feasibility of development of this system and demonstrate the approach with simulants, while during Phase I option and Phase II we`ll focus on development of a prototype for demonstration with real agentsin a certified agent lab. The development of man-portable noninvasive NBC detection device will enable personnel to detect chemical, biological, and nuclear contamination for emergency response, law enforcement and military applications.
