Abstract: An assay device for the detection of analyte in a sample, methods and immunoassay formats for performing an assay with or without the device, and methods for manufacturing the device are provided. The device is a continuous liquid flow channel having a proximal and a distal end, with a detection membrane in fluid communication with the distal end of the flow channel. Interspersed between the assay buffer and detection membrane, and continuous with the liquid flow channel, are a sample delivery means, one or more reservoirs containing the reagents necessary for conducting the assay, and, optionally, mixing or incubation reservoirs for combining the sample and reagents. The geometry of the liquid flow channel regulates the flow rate of the liquids through the channel, thereby controlling incubation, mixing and reaction time. The preferred detection membrane is an immunochromatographic test strip containing immobilized reagents.

Abstract: The invention relates to methods for producing storage-stable, latent-reactive layers and powders of surface-deactivated, solid polyisocyanates and dispersions or aqueous solutions of isocyanate reactive polymers, which can be used as adhesives and coverings. Said dispersions, suspensions or aqueous solutions can applied to a substrate in an appropriate form. Water can then be eliminated at a temperature inferior to the reaction temperature of the isocyanates and this operation can take place at a temperature above the softening temperature of the polymers. This process produces, at ambient temperature, dry and substantially water free layers which are storage stable and can react with the polymers at the polyisocyanate reaction temperature.

Abstract: Disclosed is an extremely rapidly photo-addressable storage media from inherently slow photo-addressable polymers by irradiating a substrate over a large area with a light source suitable for conventional inscription so that an optical anisotropy, i.e. a double refraction with a preferential direction in the plane of the substrate occurs. If the substrates so prepared are briefly intensively irradiated, the pattern is inscribed extremely rapidly and permanently. The invention also relates to novel side-chain polymers in which high optical anisotropy can be generated by irradiation. This optical anisotropy is very heat stable.
