The present invention relates to a method for detecting a particulate substance by immunochromatography, the particulate substance including, on its surface, a plurality of substances to be bound containing a first substance to be bound and a second substance to be bound which may be the same or different with respect to each other, wherein the method includes the steps of: (1) contacting on a membrane a sample containing the particulate substance with a first specific binding substance for the first substance to be bound to capture the particulate substance with the first specific binding substance; (2) contacting the captured particulate substance with a second specific binding substance for the second substance to be bound to label the particulate substance; and (3) detecting the labeled particulate substance, wherein the first specific binding substance is immobilized on the membrane, and the second specific binding substance is bound to a metal nanoparticle.

A test strip holder includes: a holding member at which at least a portion of a lower side of an inner periphery is a cylindrical surface having a cylindrical shape, and at whose interior a test strip is held, and at which a direction of an imaginary central axis of the cylindrical surface is a horizontal direction or a direction inclined with respect to a vertical direction; an opening portion provided in an outer surface of the holding member; a sorting member rotating at an interior of the holding member around a rotation axis that coincides with the central axis; a pushing piece projecting out from a distal end edge, which is parallel to the central axis, at the sorting member in a direction of rotation of the sorting member; and a sorting piece projecting out from a distal end of the pushing piece toward the cylindrical surface.

Example methods and systems train an end-to-end neural network machine to analyze images of lateral flow assay test strips by learning non-linear interactions among lighting variations, test strip reflections, bi-directional reflectance distribution functions, angles of imaging, response curves of smartphone cameras, or any suitable combination thereof. Such example methods and systems improve the limit of detection, the limit of quantification, and the coefficient of variation in the precision of quantitative test results, under ambient light settings.

Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.
