Multi-analyte chemical sensor array for underwater explosives detection

In this Phase I project, we will define and develop a concept for a multi-analyte sensor system to detect explosive threat compounds of interest at operationally relevant concentrations in seawater. Explosives trace detection and classification will be performed by Emitechs novel technology, which involves smart nanocomposites and multi-parametric electro-optical sensing. We will conduct a feasibility analysis and provide the conceptual design of a compact sensor array for underwater real-time detection and classification of nitro- and peroxide- based explosives. The design of a water-vapor conversion module will be selected and preliminarily tested using simulating breadboards. The number of sensory elements will be determined and the flow cell will be modified accordingly. Also, with high-level assistance from SubChem Sensor System, Inc. (our subcontractor), all necessary equipment/software for integration of the sensor array into an ROV platform will be assessed and conceptually designed. During the 6-months of the Phase I option, we will contribute to the continued progress of the project for a successful transition to Phase II. This time will be spent initiating the transition from a conceptual design to a fabricated package. A working prototype will be fabricated, tested and optimized during Phase II project performance.
