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.

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： A method of durably rendering a polymeric fabric, e.g., a polyolefin fabric, wettable and resistant to protein adsorption. The method involves providing a polymeric fabric having a surface, applying to the surface of the polymeric fabric a composition which includes water and a surfactant adapted to durably render the polymeric fabric resistant to protein adsorption, and drying the polymeric fabric. The surfactant has a solubility in water at 20.degree. C. no greater than about 5 percent by weight, based on the weight of the water, and is present on the polymeric fabric in an amount of the surfactant sufficient to reduce the adsorption of the protein by the fabric. The coated fabric not only exhibits durable reduced adsorption of protein but also has durable wettability by aqueous liquids. The coated fabric is especially suited for incorporation in such disposable absorbent articles as diapers, feminine care products, such as sanitary napkins and tampons, incontinent care products, training pants, wipes, and the like.

摘要： A nonwoven fabric is provided which is made from fibers comprising at least two thermoplastic polymers and a compatibilizer. One of the thermoplastic polymers is present as a dominant continuous phase and the other one or more polymers are present as a non-continuous phase or phases. The polymer of the non-continuous phase or phases has a polymer melt temperature less than 30.degree. C. below the polymer melt temperature of the continuous phase. The polymer of the dominant phase may be, for example, polypropylene and the non-continuous phase may be, for example, polyamide. The compatibilizer may be one of several such as zinc ionomers of ethylenemethacrylic acid or modified polypropylene with maleic anhydride. The fibers from which the fabric is made are generally between about 5 and 50 microns in diameter and the non-continuous phase may exist within the continuous phase as fibrils with a cross-sectional area at least 0.1% of the cross-sectional area of the fiber.
