  • Patent number: 9028771
    Abstract: The invention provides a modified form of saturation assay, which is based on the measurement of a free or unbound labelled reagent fraction (such that there is an increase in signal in the presence of analyte) and employs trapping zones to concentrate said unbound or free labelled fraction to avoid loss of sensitivity. Preferably, the assay is a membrane assay.

  • Publication number: 20150125346
    Abstract: Embodiments of the present invention are directed toward devices, systems, and method for conducting assays using sedimentation. In one example, a method includes layering a mixture on a density medium, subjecting sedimentation particles in the mixture to sedimentation forces to cause the sedimentation particles to move to a detection area through a density medium, and detecting a target analyte in a detection region of the sedimentation channel. In some examples, the sedimentation particles and labeling agent may have like charges to reduce non-specific binding of labeling agent and sedimentation particles. In some examples, the density medium is provided with a separation layer for stabilizing the assay during storage and operation. In some examples, the sedimentation channel may be provided with a generally flat sedimentation chamber for dispersing the particle pellet over a larger surface area.

  • Publication number: 20150125873
    Abstract: According to the invention there is provided a method of detecting an analyte including the steps of: i) providing a sample which contains the analyte and magnetic nanoparticles, in which the magnetic nanoparticles include a magnetic body portion which acts as a signalling vector and at least one receptor moiety attached to the body portion for binding to the analyte; ii) applying a magnetic field across at least a portion of the sample to orient the magnetic nanoparticles with respect to the applied magnetic field; iii) introducing electromagnetic radiation into the sample; iv) detecting a physical property which varies in dependence on the orientation of the magnetic nanoparticles with respect to the applied magnetic field, wherein the physical property is associated with the interaction of the electromagnetic radiation with the magnetic body portion which thereby acts as a signalling vector; and v) correlating the detected physical property with the presence of the analyte.

  • Publication number: 20150125965
    Abstract: Systems and methods for detecting the presence of biomolecules in a sample using biosensors that incorporate resonators which have functionalized surfaces for reacting with target biomolecules. In one embodiment, a device includes a piezoelectric resonator having a functionalized surface configured to react with target molecules, thereby changing the mass and/or charge of the resonator which consequently changes the frequency response of the resonator. The resonator's frequency response after exposure to a sample is compared to a reference, such as the frequency response before exposure to the sample, a stored baseline frequency response or a control resonator's frequency response.

  • Publication number: 20150118690
    Abstract: A sample analyzer has an illuminator for illuminating an assay sample to cause luminescence, and a support for a sample vessel containing the assay sample. The support is adapted to position the assay sample proximate the illuminator. A detector is positioned along an optical axis extending from the illuminator, through the positioned assay sample, to the detector, so as to detect the luminescence from the assay sample. A reflector is removably disposed between the illuminator and the assay sample so as to reflect a portion of the luminescence back through the positioned assay sample toward the detector.
