Pittsburgh-based ChemImage Sensor Systems have won a contract to develop a system for the US Army that will scan latent fingerprints for drug or explosive particles.The contract for the chemical fingerprint identification system (CFIS) was awarded by the Army Edgewood Chemical Biological Centre earlier this month.Tender documents released by the centre last February revealed that the CFIS should improve the army's capability to non-invasively, non-destructively collect fingerprints and identify chemical materials that may be present.”This is to directly link the fingerprint sample to the individual and detect possible threat related materials found on the persons' residual biometric.”CISS has previously worked on developing chemical imaging technologies to address the challenges associated with chemical, biological, and explosive threat detection.System requirements published by the centre in February included man-portability; 20-min time-to-result; the ability to capture a bright field image (photograph) of the entire examined sample at a level of 1000 dpi or greater; and the ability to locate, detect, and identify exogenous materials found within the minutiae and ridges of a fingerprint sample.
