Abstract: The present invention generally relates to nucleic acid-based sensors and methods for detecting volatile analytes. More particularly, this invention relates to nucleic acid-based optical sensors, sensor arrays, sensing systems and sensing methods for intelligent sensing and detection of unknown materials by way of real-time feedback and control of sampling conditions.

Abstract: The invention relates to a chemical sensor, sensing system and sensing method which provides for a multi-sensor, cross-reactive, sensor array having a rapid response time, dynamic modulation of sampling parameters, and real-time feedback control of sampling and detection conditions. The device and method provide for smart detection and discrimination of analytes in fluids through intelligent sampling, detection, and control algorithms. The invention further provides for a sensor array having discrete sensor elements dispersed on fluid-permeable, high surface area, porous, textured substrates. The innovative device and method exhibit high sensitivity, discrimination and detection capability for target analytes at ppb and sub ppm concentrations.

Abstract: The present invention is an optical detection and identification system and provides an optic sensor, an optic sensing apparatus and methodology for detecting and evaluating one or more analytes or ligands of interest, either alone or in admixture. The optic sensor of the system is comprised of a supporting member and an array formed of heterogeneous, semi-selective thin films which function as sensing receptor units and are able to detect a variety of different analytes and ligands using spectral recognition patterns.
