    摘要: The degradation over time that is commonly seen with analyte-binding proteins when used as sensors for trace amounts of an analyte in a gaseous mixture is reduced by maintaining the sensor in a low-oxygen or oxygen-free environment.

    摘要: Highly sensitive devices for detecting nitric oxide and/or other gaseous analytes in gaseous samples are improved by the incorporation of a carbon monoxide scavenger in the interior of the device or in the device packaging. The release of carbon monoxide within the housing of the device by the plastic used in the construction of the housing or by anything within the device that releases carbon monoxide causes a loss in sensitivity due to competition between the carbon monoxide and the nitric oxide for the binding sites on the device sensor. The scavenger corrects this by either catalyzing the oxidation of carbon monoxide to the less competitive carbon dioxide or immobilizing the carbon monoxide by affinity-type or covalent binding. Analogous effects are achieved for analytes other than nitric oxide but that likewise encounter interference from carbon monoxide in binding to sensors.

    摘要: A sensor and method for making a sensor includes providing a substrate having an adhesion layer with a first functional group operatively associated with a sol-gel composition having a second functional group, and at least one linker material for connecting the first functional group to the second functional group. In another embodiment, a sensor and method for making the sensor includes providing a sol-gel layer operatively associated with a sol-gel precursor solution that includes at least one co-polymer and at least one solvent adapted to resist the deformation of the sol-gel layer by decreasing evaporation, decreasing cross-linking, increasing intermolecular forces, or increasing elasticity.
