    摘要： A diagnostic method and associated test kit for detecting an analyte residing in a test sample is provided. The kit includes a housing, and a membrane disposed within the housing having a detection region and a collection region. A blood sample meter is provided having a first end for absorption of a blood sample, a filtering section adjacent to the first end that filters red blood cell components from the blood sample, and a storage section adjacent to the filtering section that receives plasma or serum from the filtering section. An opening in the housing is sized for insertion of the sample meter into the housing such that the storage section of the sample meter is disposed in fluid communication with the collection region of the membrane. The plasma or serum is transferred from the storage section of the sample meter to the collection region of the membrane for subsequent migration to the detection region.

    摘要： Disclosed is a process for disinfecting water which provides a visual indication after the disinfection is complete. First, the water to be disinfected is generally simultaneously intermixed with at least three items. The items are: (1) a disinfectant which is adapted to render harmless substantially all pathogens present in the water upon the disinfectant being intermixed with the water for a time period T.sub.k ; (2) a colorant; and (3) a material which can remove substantially all of the disinfectant and colorant from the water over a time period t.sub.r, where T.sub.r is greater than T.sub.k. Secondly, the water, disinfectant, colorant and the removing material are allowed to remain intermixed for a time period of T.sub.r or greater. At the end of the time period T.sub.r, substantially all pathogens in the water will be rendered harmless, substantially all of the disinfectant will be removed from the water and substantially all of the colorant will be removed from the water. As a result of the removal of the colorant, the water will become uncolored which will give the consumer a visual indication after the disinfection process is complete and the water is safe to drink. Articles for use in carrying out the process are also disclosed.

    摘要： An enhanced diffraction based biosensor system and method are provided for detecting an analyte of interest in a test medium. The system incorporates at least one additional detection tag substance with the analyte of interest, the tag emitting a measurable parameter that is different from optical diffraction characteristics of the analyte. The biosensor may be a “fluoroptical” system wherein the detection tag is a fluorescence emitting substance, including fluorescent-labeled diffraction enhancing elements. The enhanced diffraction biosensor system may determine the presence of analytes in biological fluids both qualitatively and quantitatively.

    摘要： An adsorbent filter for removing caffeine from liquids. The filter is composed of a matrix of fibrous material; and adsorbent particulate material integrated within the matrix of fibrous material, so that passage of a liquid having a caffeine concentration ranging from about 20 to about 100 mg per 100 mL of liquid through the matrix for a contact time of less than about 2 minutes results in at least a 40 percent reduction in the caffeine concentration of the liquid. The matrix of fibrous material may be selected from woven fabrics, knit fabrics and nonwoven fabrics. The adsorbent material may be clay minerals such as, for example, smectite clay minerals. Examples of smectite clay minerals include, bentonite clays and montmorillonite clays. Generally speaking, the filter can be adapted to provide at least a 40 percent reduction in the caffeine concentration for about 1 cup to about 40 cups of a liquid.

    摘要： The present invention provides an inexpensive and sensitive system and method for detecting analytes present in a medium. The system comprises a diffraction enhancing element, such as functionalized microspheres, which are modified such that they are capable of binding with a target analyte. Additionally, the system comprises a polymer film, which may include a metal coating, upon which is printed a specific, predetermined pattern of a analyte-specific receptors. Upon attachment of a target analyte to select areas of the polymer film, either directly or with the diffraction enhancing element, diffraction of transmitted and/or reflected light occurs via the physical dimensions and defined, precise placement of the analyte. A diffraction image is produced which can be easily seen with the eye or, optionally, with a sensing device.
