摘要: Disclosed are methods and systems for detecting a target gas, which involve a configuration of a light source (120) and paper tape (110) such that light (112) emitted from the light source (120) can transmit through the paper tape (110). At least some of the portion of light (112) which transmits through a paper tape (110) can be detected with a detector (130). Detection of the light (112) can be used to determine presence or absence of low concentrations of the target

摘要: An assay device is disclosed comprising a housing (10) and a test portion (2), electronic circuitry (30) and an optical assembly (41), each at least partially located in the housing (10). The test portion (2) comprises one or more test zones (2E, 2F) adapted to receive an analyte (22) and a fluorescent label associated with the analyte, the fluorescent label being excitable by excitation light and adapted to emit emission light upon excitation by excitation light. The electronic circuitry (30) comprises one or more light sources (31, 32) and one or more light detectors (33). The optical assembly (41-44) comprises one or more excitation light guides (41, 44) adapted to guide excitation light from the one or more light sources (31, 32) to the one or more test zones (2e, 2f), and/or one or more emission light guides (43, 44) adapted to guide emission light from the one or more test zones (2e, 2f) to the one or more light detectors (33). The sets of emission light guides (43, 44) and excitation light guides (41, 44) may also take the form of individual integral one-piece light guide units where the emission light guide unit rests within the excitation light guide unit.

摘要: The present invention provides a sensor for detecting or quantifying a target substance contained in a liquid sample. The sensor comprises a quinone compound that accepts electrons released as a result of dehydrogenation or oxidization of the target substance by the enzyme; and at least a pair of electrodes, wherein the quinone compound contains a quinone and a substituent, wherein the substituent is hydrophilic. The quinone compound has a lower redox potential than conventional substances, so interfering substances have less effect on detection results with this sensor, particularly the redox potential of the quinone compound measured using a silver/silver chloride (saturated potassium chloride) electrode as a reference electrode is more negative than the oxidization potential of ascorbic acid.

摘要: An improved optical detection unit for an assay device, such as a lateral flow device, for the quantitative determination of the concentration of an analyte in a liquid sample, and an assay device comprising the same. The detection unit comprises an organic light emitting diode (OLED) emitter that has an emission spectrum E within the wavelength range from λ1 to λ2, and an organic photodiode detector (OPD) that has a light detection spectrum S within the wavelength range from λ1 to λ2. The detection unit has a test region that comprises a light absorbing component that has an absorbance spectrum A within the wavelength range from λ1 to λ2. The test region is positioned adjacent to the emitter and the detector to form an optical pathway from the light emitting diode to the photodiode through at least a portion of the test region. Formula M defines a relationship between E, S and A, and M is less than about 0.4.

摘要: A portable in-vitro (PIV) diagnostic detector operable to perform a fluorescence assay on a sample in one or more detection chambers of a cartridge is provided. The PIV diagnostic detector comprises a first optical module which includes (i) an LED light source for emitting substantially monochromatic light to illuminate a detection zone associated with at least one detection chamber; (ii) an excitation filter interposed between said light source and said detection zone; (iii) a light detector operable to detect fluorescent light emitted by an excited fluorescent label associated with the sample and to measure an intensity of the fluoresced light; and (iv) an emission filter interposed between said light detector and said detection zone. The (PIV) diagnostic detector further comprises a microprocessor operable to process the measured intensity of the fluoresced light to determine whether an analyte is present in the sample; wherein the first optical module is configured such that a longitudinal axis of the light source extends at an oblique angle with respect to a longitudinal axis of the light detector.
