    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.

    摘要翻译： 提供了一种快速检测宿主感染性结膜炎的方法。 该方法包括使眼睛测试样品与在微生物存在下显示颜色变化的色原体（例如，Reichardt's染料）接触。 本发明人已经发现，颜色变化的程度可以根据微生物是细菌还是病毒而变化。 不期望受理论的限制，本发明人相信色原体与细菌的基于聚肽聚糖的细胞壁结构相互作用以诱导在感染水平上更加明显的颜色变化。 相信这种相互作用在细菌中比在病毒中更大程度地发生。 因此，虽然染色体在病毒存在的情况下仍可能发生颜色变化，但通常其程度要小得多。 以这种方式，在本发明中可以使用色原体的颜色变化程度作为区分病毒和细菌性结膜炎的机制。

    摘要： An absorbent pad configured for placement under a patient to absorb bodily fluids includes a liquid permeable cover layer, a liquid impermeable back sheet, and an absorbent structure disposed between the cover layer and the back sheet. At least one of the cover layer, back sheet, or absorbent structure incorporates a dried application of a liquid activated carbon ink having activated carbon, a binder, and a solvent, with the dried application of ink having a solids add-on level of at least about 2%. The activated carbon ink is applied in a pattern over between about 25% to about 95% of a total upper surface area of the pad and presents a visually contrasting color against a background color of the pad or a contrasting ink.

    摘要： A technique for detecting the presence of microorganisms in a simple, rapid, and efficient manner is provided. More specifically, the technique involves identifying one or more volatile compounds associated with a particular microorganism of interest. The volatile compounds may be identified, for instance, using solid phase microextraction in conjunction with gas chromatography/mass spectroscopy (“GC/MS”) analysis methods. Once identified, an indicator may then be selected that is configured to undergo a detectable color change in the presence of the identified volatile compound(s). If desired, the indicator may be provided on a substrate to form an indicator strip for use in a wide variety of applications. In this manner, the presence of the microorganism may be rapidly detected by simply observing a color change of the indicator strip.

    摘要： An elastomeric article that contains a chromogen that undergoes a detectable change in color in the presence of one or more microbes is provided. For example, in one embodiment, the chromogen is a solvatochromic dye (e.g., Reichardt's dye) that undergoes a color change in the presence of bacteria or other microbes. More specifically, such dyes may respond 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.

    摘要： An apparatus for slush molding a thin shell having an outer layer and an inner layer. The apparatus includes two tubs alternately movable to a cast position for dispensing their respective material contents into a mold cavity. According to another embodiment of the invention, the apparatus includes a diverter valve configured to alternately open a passage from each of two tubs to the mold cavity to selectively dispense charge materials from the respective tubs into the mold cavity. In addition, a method is provided for forming a thin shell having an outer layer and an inner layer. A first polymer material is cast and allowed to melt on a heated mold surface to form an outer layer. A second polymer material is then cast and allowed to melt and form an inner layer on the inner surface of the outer layer. The shell is then removed from the mold.
