Abstract:

ChemImage Biothreat LLC ChemImage in collaboration with the Edgewood Chemical Biological Center ECBC and the Armed Forces Institute of Pathology AFIP have teamed on a 1 year project entitled Optical Detection of Biological and Chemical Threats in Water and Food, to develop and validate waterborne pathogen detection technology in support of the Joint Services Advanced Water Monitoring JSAWM Program. The optical detection of waterborne threats project integrates proven Raman Chemical Imaging RCI and sample pre-concentration technology to collect, enrich, detect and identify CB threats in water and food. The objective of this program has been to advance the state-of-the-art in detection and identification of biological and chemical threat materials in water and food. Improved collection concentration focused on the use of tangential flow filtration TFF coupled with centrifugation. Biological materials used in this program were supplied by AFIP. AFIP also operated RCI equipment in their BSL-2 laboratory for limited sample quality evaluation. Hazardous chemical materials used in this program were supplied by ECBC for analysis within their secure facilities. Additionally ECBC personnel worked with ChemImage personnel in developing protocols for the analysis of water samples including the construction of receiver operator characteristic ROC curves.
