  • Publication number: 20120232419
    Abstract: A high-sensitivity analyzer for nitric oxide in exhaled breath at levels of 200 ppb or less with a sensor containing cytochrome C is rendered capable of multiple uses without the need for installing a new sensor for each use. This capability is achieved by regenerating the analyzer after each use by purging the sensor and surrounding regions with NOx -free air in a controlled manner, preferably in pulses separated by equilibration periods.

  • Patent number: 7611671
    Abstract: 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.

  • Patent number: 7393693
    Abstract: 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.

  • Patent number: 7278291
    Abstract: 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.

  • Publication number: 20030180964
    Abstract: A sensor element is formed from a sensing material immobilized by covalent bonding, such as nitrogen-carbon bonding, to a sol-gel glass or sol-gel copolymer to reduce leaching. A method of manufacturing such a sensor element involves covalently bonding the sensing material with the sol-gel precursor before hydrolysis of an organic silicate used in the process, or after the sol-gel matrix formation. Alternatively, the sol-gel can be surface treated to generate functional groups that facilitate the covalent bond formation.
