    摘要: A clinical testing assay device that can differentiate bacterial from viral infections is described. The assay device has a sample contact zone with an absorbent pad on which a test sample is deposited and a detection zone with a colorant indicator that is sensitive to bacteria cells. The colorant indicator changes color when exposed to a bacteria sample. The color change signal can manifest relatively quickly, usually within a few minutes, and with an intensity correlative to the concentration of bacteria in a test sample. A method of use is also provided.

    摘要: A vaginal treatment composition that rapidly forms a gel when placed into contact with monovalent or polyvalent cations, such as sodium (Na+) and calcium (Ca2+) cations naturally found in vaginal mucosa, is provided. The gel may form in less than about 1 hour, in some embodiments less than about 1 minute, and in some embodiments, less than about 30 seconds. Among other things, such rapid gelation reduces the likelihood of leakage during use. In addition, because the gel may form intravaginally, it is more likely to retain its structure and shape over an extended period of time. In this manner, the gel may provide the prolonged release of a therapeutic agent that inhibits and/or treats vaginal infection. For instance, the gel may remain within the vagina for about 2 to about 48 hours to provide the desired effect.

    摘要: A method for detecting a microorganism or class of microorganisms is provided. More specifically, the method employs an array that contains a plurality of discrete regions (referred to as “addresses”) spaced apart on a solid support in a predetermined pattern. The addresses are selected so that the array provides a distinct spectral response (e.g., pattern of colors) or “fingerprint” for a particular microorganism or class of microorganisms. For example, the array may provide a certain spectral response in the presence of one microorganism or class of microoryanisms (e.g., gram-negative bacteria), but provide a completely different spectral response in the presence of another microorganism or class of microorganisms (e.g., gram-positive bacteria). Detection of the spectral response provided by the array may thus allow for differentiation between microorganisms.

    摘要: A material composition including a flexible, polymeric matrix and a reverse-thermochromic colorant is described. When subjected to a heat source, the polymeric material can change color from a pale or neutral color to a darker or more vibrant color of a Delta E (ΔE) change of >3. The reverse-thermochromic colorant exhibits a color change when exposed to a heat source within a period of about 30 seconds, and is observable by an unaided human eye under either natural daylight or ambient artificial normal lighting conditions. One or more different reverse-thermochromic colorants in combination may be incorporated. The polymeric matrix surrounds or encapsulates a solvatochromic dye molecule with a phenolate betaine structure. The polymeric matrix includes a dipole orientating agent that induces said solvatochromic dye to express locally when subjected to a temperature change. Various uses for the composition and articles that incorporate the composition are also described, in addition to a method of indicating the temperature of an object or environmental condition.
