Abstract: The invention provides an improved method for sensitive and specific detection of target molecules, cells, or viruses. The inventive method uses large area imaging to detect individual labeled targets complexed with a target-specific selection moiety. The invention eliminates wash steps through the use of target-specific selection through one or more liquid layers that can contain optical dye and density agents. By eliminating washes the invention simplifies instrumentation engineering and minimizes user steps and costs. The invention uses sensitive image analysis to enumerate individual targets in a large area, is scalable, and can be deployed in systems ranging in complexity from manual to highly automated.

Abstract: The present invention is directed to devices and methods using pan-generic antibodies to detect bacteria in a sample. The invention relates to binding assays, especially immunoassays, utilizing a multivalent binding agent immobilized on a particle. The invention also relates to the surprising discovery that increasing the size of the particles improves the sensitivity of the screen.

Abstract: A capillary flow device useful in double capture assays, such as double capture immunoassays, and a double capture assay. The capillary flow device comprises a capillary track, a sample receptacle, a particle collecting means and, optionally, a magnet and a particle concentrator. The assay method is useful for determining any analyte of interest for which there is a specific binding partner.
