Abstract
Not Available Triton Systems, Inc., proposes to apply its innovative electrochemical deposition method for fabricating field use-compatible vapor and aerosol concentrations monitors that provide significantly improved species selectivity. This proprietary process, with which we have succeeded in upgrading dramatically the performance of an electrochromic polymer-based switch for rf electromagnetic waves, allows formation from its appropriately functional group-altered monomer of virtually any electroactive polymer, rather than the very few that lend themselves to casting from solution. Triton is therefore able to design miniaturized conductimetric chemisensors with bandgaps tailored for differential response to the redox potentials of chemical-biological warfare components and ambient interferents. We are able to confine deposition of the polymer film to the spaces between interdigitated metallic electrodes by making use of a company-developed thermally activated mask. This production method both allows precise control of the (submicron) thickness of this volatiles-sensitive layer and further increases its change in resistance with analyte arrival rate by giving it a highly porous exposed surface. The objective of Triton's research will be to formulate robust, long shelflife sub-ppm threshold response microsensors with enhanced discrimination of specific airborne CBW agents and precursors. Conductive polymer-based vapor concentration sensors are currently being applied for assessing the quality of food products and their as-received raw materials, the protection provided by packaging, and the threat from noxious and hazardous gases or aerosols in workplaces (among others, pesticide-treated areas and the ESA / MIR Space Station crew cabin). Further applications in chemical process control and olfactory medical diagnosis are under development, as are those in the several aspects of detecting toxic agents. The improved species selectivity, threshold sensitivity, and overall robustness of Triton's innovative chemisensor will significantly improve the effectiveness and broaden the scope of this automatic concentration monitoring.
