20130203183 | ASSAY DEVICE - An assay device for performing an assay on a liquid sample using a detection conjugate capable of binding to an antigen and containing a label. The device includes a substrate surface having a sample addition zone, a reaction zone and an absorbing zone, the zones being connected by at least one fluid passage, wherein the device has a first functionality verifying feature located between the sample addition zone and the reaction zone, and a second functionality verifying feature located within the absorbing zone. Both functionality verifying features are capable of undergoing a detectable change when contacted by the sample, in which the assay device further includes at least one alignment verification zone. There is further provided a kit of parts and a method of conducting an assay. | 08-08-2013 |
20120028818 | MICRO FLUIDIC STRUCTURES - A micro fluidic system includes a substrate, and, provided on said substrate, at least one flow path interconnecting with functional means in which liquid samples can be treated by desired procedures. The flow paths are laid out to form a pattern for the transport of liquid samples to and from said functional means. These flow paths comprise a plurality of micro posts protruding upwards from said substrate, the spacing between the micro posts being small enough to induce a capillary action in a liquid sample applied anywhere within any of said flow paths, so as to force said liquid to move from where said liquid sample was applied. | 02-02-2012 |
20110306519 | METHOD OF FORMING POLYMERIC MICROARRAY SUPPORT - In combination, a polymeric microarray support for an optical assay arrangement, that includes an optical detection instrument having a known depth of focus for detecting light emitted from said microarray support. The polymeric microarray support has a support surface made from a polymeric support material having a thickness varying over the area of the support surface by a thickness variation value. The said support includes formed microfeatures made up of grooves arranged to have a predetermined depth at the time of forming, the groove depth being selected based on the depth of focus of the optical detection instrument and the thickness of the support. The sum of the depth for the grooves and the thickness variation value of the polymeric support surface substantially corresponds to the depth of focus of the optical detection instrument in order to reduce noise, the polymeric support surface having attached thereto probe molecules to form binding sites. | 12-15-2011 |
20110117674 | ASSAY METHOD AND DEVICE - A method for the analysis of at least two analytes in a liquid sample, in which a substrate is provided wherein at least two different types of capturing molecules are immobilized on the substrate and wherein each type of capturing molecule has specific affinity for an analyte. The sample is contacted with capturing molecules, wherein for at least one analyte to be analyzed contact is induced between the capturing molecules and a labelled detection molecule with specific affinity for the analyte, and for at least one another analyte to be contact is induced between the capturing molecules and a labelled version of the analyte. A detectable signal is measured from the labelled detection molecule and the labelled analyte on the substrate, wherein the concentration of the labelled analyte is adapted to the concentration of the analyte in the sample. | 05-19-2011 |
