    摘要: Skin sealants are usually applied over skin preps to seal the skin and hold any remaining bacteria in place prior to surgical incisions. This sealant is generally left on the skin after surgery. A skin coating is provided that has an indicator that gives a visible color change upon contact with microbes or microbial by-products and so provides an early warning of infection. The coating is a curable coating composition that may also be used without skin preps and may be used to protect other disruptions in the skin like wounds, bruises, abrasions, burns, acne, blisters, bites, stings, punctures and cuts. It may also be used to close wounds or provide an additional barrier to other parts of the skin, such as the nails and mucosa.

    摘要: A method for semi-quantitatively or quantitatively detecting the presence of a microbe in a sample is provided. The method utilizes a test dye that undergoes a detectable color change in the presence of one or more microbes. For example, in one embodiment, the test dye is a solvatochromic dye (e.g., Reichardt's dye) that responds to differences in polarity between microbe components (e.g., cell membrane, cytoplasm, etc.) and the environment outside the cell. Alternatively, other mechanisms may be wholly or partially responsible for the interaction between the dye and the microbe, such as acid-base reactions, redox reactions, and so forth. Regardless, the color of the test dye may be compared to the color of a control dye, wherein the color of the control dye corresponds to a known microbe concentration.

    摘要: A graphic and/or message display system is described. The graphic and/or message display system functions to develop over a period of time a hidden graphic or message on an indicator panel or display area. The hidden graphic or message is revealed when an obscuring graphic reacts with a solvent to change color become at least substantially transparent. The graphic and/or message display system may be used as a stand-alone device or may be incorporated as part of various articles or products, for instance, as a positive reinforcement or a reminder to perform a task. Methods for using the graphic and/or message display system are also described.

    摘要: A vaginal treatment composition that employs a therapeutic agent to inhibit and/or treat vaginal infection is provided. The therapeutic agent is capable of inhibiting and/or killing Gardnerella (e.g., Gardnerella vaginalis), Candida (e.g., Candida albicans), and/or Trichomonas (e.g., Trichomonas vaginalis) pathogens. Desirably, such antimicrobial efficacy is achieved without substantially inhibiting the growth of Lactobacillus acidophilus. For instance, sugars and/or sugar alcohols may be employed in the present invention as a therapeutic agent for inhibiting and/or treating vaginal infection. In one particular embodiment, D-xylitol is used as the therapeutic agent.

    摘要: Suitable dyes are used herein to indicate the presence of microbial contamination by spraying them onto surfaces in the form of an aqueous solution. The dye solution may also be allowed to dry, thus producing the dried residue of an aqueous solution. It's believed that these dyes change color in response to a change in polarity of the environment. Since water is a polar solvent and most bacteria are made from non-polar substances, the presence of bacteria changes the polarity of the environment, triggering a change visible by the unaided eye.

    摘要: Solvatochromic dyes are used herein to indicate the presence of bacteria by incorporating them into various substrates such as films, woven and nonwoven fabrics, paper towels, coform and airlaid materials and bonded carded webs. These dyes change color in response to a change in polarity of the environment. Since water is a polar solvent and most bacteria are made from non-polar substances, the presence of bacteria changes the polarity of the environment, triggering a change visible by the unaided eye. A lateral flow device incorporating solvatochromic dyes and a method of detecting bacteria are also included.

    摘要: A method for rapidly detecting infectious conjunctivitis in a host is provided. The method includes contacting an ocular test sample with a chromogen (e.g., Reichardt's dye) that exhibits a color change in the presence of a microbe. The present inventors have discovered that the extent of the color change may vary depending on whether the microbe is a bacteria or virus. Without intending to be limited by theory, the present inventors believe that the chromogen interacts with the peptidoglycan-based cell wall structure of bacteria to induce a color change that is even more apparent at infectious levels. It is believed that this interaction occurs to a much greater extent in bacteria than in viruses. Accordingly, although the chromogen may still undergo a color change in the presence of the viruses, it is typically to a much lesser extent. In this manner, the degree of color change of the chromogen may be used in the present invention as a mechanism for differentiating between viral and bacterial conjunctivitis.

    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.
