Small Molecule Vapor Chemical Detection System using a low power and low cost MEMS based chemiresistor sensing Array

Seacoast Science, Inc. (SCS) proposes the research and development of polymers and materials for the rapid and sensitive detection of low molecular weight toxic industrial compounds (TICs) and other compounds of interest. These sensitive materials will be selected from a broad class of linear, hyperbranched, and network materials. The relative response of the materials will be used in a Quantitative Structure Property Relationship (QSPR) study and the first generation materials will be modified using the calculated interaction of the analytes with the material surface. Other metrics to evaluate the materials on the sensor platform are reversibility, baseline stability, and long-term The final optimization of these materials will allow the development of a sensor system will allow the real-time detection of a range of compounds from low molecular weight TICs to CWAs and explosives.
