  • Publication number: 20190234877
    Abstract: A method of testing a sample for the presence of nitrate or nitrite, the method comprising the steps of: forming a mixture by contacting the sample with a composition comprising hydrogen peroxide or a hydrogen peroxide precursor and a fluorescent indicator precursor capable of forming a fluorescent indicator in the presence of peroxynitrite; irradiating the mixture; and measuring fluorescence from the fluorescent indicator. The method may be carried out using a device in which the mixture in a channel or chamber 101 of a microfluidic device is irradiated by light from light source 103 and emission from the fluorescent indicator is detected by photodetector 105.

  • Publication number: 20190219750
    Abstract: A sensor comprising a light source (103); a photodetector (105); a sample receptacle such as a microfluidic device (101) between the light source and the photodetector; and one or both of a first light filter (107) and a second light filter (109) wherein the first light filter is provided between the sample receptacle and the photodetector and the second light filter is provided between the sample receptacle and the light source. The first light filter may comprise tartrazine. The second light filter may comprise Coomassie violet R200, Victoria Blue B or acid fuchsin. In use, light h?1 emitted from the light source is absorbed by a luminescent indicator in the sample receptacle which then emits light h?2 detected by the photodetector.

  • Publication number: 20190162730
    Abstract: A method of testing a liquid sample for the presence of an analyte, the method comprising the steps of: forming a mixture by contacting the sample with a composition comprising an oxidase for formation of hydrogen peroxide from the analyte, a fluorescent indicator precursor capable of forming a fluorescent indicator in the presence of an oxygen radical and an iron compound wherein the iron compound is dissolved in the mixture; irradiating the mixture; and measuring fluorescence from the fluorescent indicator. The method may be carried out using a device in which the mixture in a channel or chamber (101) of a microfluidic device is irradiated by light from light source (103) and emission from the fluorescent indicator is detected by photodetector (105).

  • Publication number: 20190033303
    Abstract: A sensor for detection of a target species is provided. The sensor includes a capture layer on an organic semi-conductor to which biomolecules may be bound. The capture layer polymer is deposited from a non-aqueous solution and the polymer is insoluble in water and has reactive groups for interaction with the analyte directly or via a conjugated species. Organic electronic devices, for example organic thin-film transistors having the capture layer are also provided. Use of a capture layer provides a low cost high quality biosensor which may be reliably produced in large quantities.

  • Publication number: 20170285018
    Abstract: A method of forming a sensor comprising a single layer or multilayer structure; a fluorinated layer having a fluorinated surface on the single layer or multiple layer structure; and a receptor having a fluorinated group on the fluorinated surface, the method comprising treating the fluorinated surface with a surfactant and either depositing the receptor having a fluorinated group onto the fluorinated surface from a formulation comprising one or more solvents in which the receptor is dissolved or dispersed, or depositing a fluorinated compound comprising a fluorinated group onto the fluorinated surface from a formulation comprising one or more solvents in which the fluorinated compound is dissolved or dispersed, and reacting the fluorinated compound or a derivative thereof with a receptor comprising a reactive group to form the receptor having the fluorinated group.
