Abstract: Methods and systems are provided making a porous nitrocellulose strip for use in a lateral flow test. The strip may be formed from a liquid polymer mixture dispensed onto the planar surface via a dispensing device positioned vertically above the planar surface. The strip may be printed with a microarray of binding ligands for use in the lateral flow test. Methods and systems are further provided for developing and viewing the results of the assay.

Abstract: An apparatus for performing immunoassays employs a microtiter tray having wells coated with a specific binding partner in conjunction with an array of magnets disposed below the tray. A device for providing relative circular motion of the tray and magnetic array so as to provide a magnet field to the well walls for attracting magnetic particles and subsequent movement of the magnetic field.

Abstract: The present invention relates to a process for determining or detecting by immuno adherence a biological substance present in a sample, which consists in introducing the sample into a receptacle on whose walls there is a component which has a specific immunological affinity for the substance to be tested for, in adding magnetic particles on which there is a substance which has a specific immunological affinity for the substance to be tested for, in subjecting them to several successive magnetic actions in order to accelerate the deposition of the said particles onto the walls and to displace those which have not formed specific bonds with the substance to be tested for which adheres to the walls via the component with affinity which is fixed thereto, and in observing the particles deposited.
