The device detects compounds transported through its enclosure, even compounds carried by human breath or emanating from human skin.
About
Multi-color, optical spectrometer for detecting explosive, hazardous, and drug materials, as well as volatile organic compounds. Key Features: Simultaneous detection of multiple species of gas molecules, such as: Compounds common in explosives (e.g. TNT based, RDX based, and TATP based explosives) Illicit drugs Hazardous materials Patient’s breath, skin, or bodily fluid Higher selectivity and specificity Lower Limit-of-Detection (e.g. LOD of ammonia <2 ppb at the 99.97% confidence level) Applications: Military, defense, and law enforcement sectors Medical diagnostics and screening (e.g. diabetes, breast cancer) Environmental science (e.g. soil, water, and ambient air contamination) Project Summary: Arkansas State University is developing and seeking collaborators and/or licensees for further development of a multi-color cavity ring-down laser absorption spectrometer (CRDS) and detection method. The spectrometer performs real time measurements and detection of multiple species of compounds in less than 5 seconds. The device detects compounds transported through its enclosure, even compounds carried by human breath or emanating from human skin. The present technology efficiently solves several challenges and limitations of pre-existing CRD methods and existing laser instruments. The multi-color optical spectrometer provides a greater level of selectivity and real time capability by allowing simultaneous measurements of multiple wavelengths. In one example, the LOD of ammonia (NH3) was demonstrated to be less than 2 ppb by volume at the 99.97% confidence level. Potential Markets Overview: The global market for environmental sensing and monitoring technologies was worth $9.1 billion in 2008 and is expected to reach $13 billion in 2014 (Sensors 2009, Volume 9, Issue 12, pp. 10447-10512). The personalized medical diagnostics global market is expected to be more than US$ 30 Billion by 2018. Diabetes management tests and cancer management tests are the leading markets in this segment (Renub Research). Patent Status: Patented. Commercialization Status: Proof of concept achieved. Seeking collaborators or licensees for further development.
