| 20090155122 | Multi-Layered Devices for Analyte Detection - A multi-layered device for detecting the presence or absence of an analyte within a test sample is described. The device includes a sensing layer and a control layer. The sensing layer is configured to support a reaction so as to exhibit a signal indicative of the presence or absence of the analyte in the test sample. The control layer is in fluid communication with and vertically adjacent to the sensing layer and includes a reagent capable of inhibiting the reaction and/or other unwanted side reactions at the sensing layer after a certain period of time by diffusive movement of the reagent from the control layer to the sensing layer. | 06-18-2009 |
| 20090129977 | HYDROGEN PEROXIDE INDICATOR AND METHOD - The present invention provides a hydrogen peroxide indicator that includes a substrate on which is disposed an indicator composition that includes at least one of a select group of colorants. As a result of contact with hydrogen peroxide, the colorants change color, and even become colorless, thereby providing an indication of the presence of hydrogen peroxide. | 05-21-2009 |
| 20080274014 | Diagnostic Device for Testing Hydration and Other Conditions - Devices for the non-invasive collection of a liquid sample in small quantities, such as urine for testing hydration in infants and incontinent adults, directly at the source of that sample, isolation of the collected sample from a testing site, the transportation of that sample to a site for testing contained within the device itself, and the selective application of some or all of the specimen to a testing apparatus contained within the device itself, with a minimum of specimen handling required. Other aspects include a method and device for facilitating the reading of the result of the specimen test by a skilled or unskilled user, including means for determining that no adequate sample has been delivered to the testing site. | 11-06-2008 |
| 20100260642 | METHOD AND DEVICE FOR LAMINAR FLOW ON A SENSING SURFACE - Methods and devices are provided for controlling a fluid flow over a sensing surface within a flow cell. The methods employ laminar flow techniques to position a fluid flow over one or more discrete sensing areas on the sensing surface of the flow cell. Such methods permit selective sensitization of the discrete sensing areas, and provide selective contact of the discrete sensing areas with a sample fluid flow. Immobilization of a ligand upon the discrete sensing area, followed by selective contact with an analyte contained within the sample fluid flow, allows analysis by a wide variety of techniques. Sensitized sensing surfaces, and sensor devices and systems are also provided. | 10-14-2010 |
| 20090246079 | STERILIZATION WRAPS AND METHODS FOR STERILIZING ARTICLES - There is provided an improved sterilization wrap and a method for using the improved sterilization wrap to sterilize an article. The wrap is made of at least a first panel of sterilization material and includes an additional panel of material. The first panel is multi-layered and includes at least one pathogen filtration layer. The first panel is rectangular and has an outer periphery and a central portion. The outer periphery includes first, second, third and fourth edges. The additional panel of material is bonded to the first panel, approximately at a forty-five degree angle to the first panel, with a substantial portion of the additional panel being adjacent to the central portion of the first panel. The perimeter of the additional panel is smaller than the perimeter of the first panel. Portions of the additional panel are bonded to the first panel along the first, second, third and fourth edges of the first panel. The article to be sterilized is placed on the additional panel, is wrapped, and sterilant is applied to the wrapped article. A chemical visual indicator is provided to indicate whether or not the article has been exposed to adequate sterilization conditions. | 10-01-2009 |
| 20100166604 | COLORIMETRIC SENSOR ARRAYS BASED ON NANOPOROUS PIGMENTS - A colorimetric array includes a substrate, a first spot on the substrate, and a second spot on the substrate. The first spot includes a first nanoporous pigment that includes a first nanoporous material and a first immobilized, chemoresponsive colorant. The second spot includes a second nanoporous pigment that includes a second nanoporous material and a second immobilized, chemoresponsive colorant. The first nanoporous pigment is different from the second nanoporous pigment. | 07-01-2010 |
| 20090060782 | METHOD FOR BONDING SUBSTRATES, METHOD FOR FORMING CHIP, AND CHIP - A method for bonding a first substrate and a second substrate includes the steps of forming the main body of at least one of the first substrate and the second substrate from an optically transmissive material that transmits light, forming at least part of the bonding faces of the first substrate and the second substrate from a thermoplastic resin that contains an optical absorption agent that absorbs light, and bonding the first substrate and the second substrate together by irradiating the optical absorption agent of the bonding faces with light via the substrate that transmits light. | 03-05-2009 |
| 20090074613 | APPARATUS FOR DISTINGUISHING BETWEEN AIRCRAFT CONSUMABLES | 03-19-2009 |
| 20100215542 | TISSUE PAPER WITH PH-INDICATOR FUNCTION - The present invention relates to a tissue paper with pH-indicator function, specifically a toilet paper that can be used to diagnose abnormal pH changes of the human urine as accompanying for instance acetonemic vomiting or diabetes. | 08-26-2010 |
| 20100021342 | METHOD AND APPARATUS FOR LIGHTED TEST STRIP - A test strip with a sample chamber is secured to a meter. The sample chamber in the portion of the test strip that extends out of the meter is illuminated by transmitting light from a light source inside the meter internally through the test strip towards the sample chamber. By way of analogy, the test strip acts in a fashion similar to a fiber optic cable or optical wave guide by transmitting the light from the meter to the remotely located sample chamber that extends outside the meter. The user is then able to easily see the sample chamber of the test strip in dark conditions so that the user is able to readily align the sample chamber with the drop of fluid on the skin as well as view the sample chamber in order to ensure proper filling. The light also illuminates a test strip slot into which the test strip is inserted. | 01-28-2010 |
| 20100129258 | FUNCTIONALIZATION OF A SUBSTRATE SYSTEM AND METHOD - Disclosed herein are embodiment relating to a methods of obtaining a functionalized porous or fibrous solid substrate with the chemical and/or physical properties of a nano-structured molecular or polymer chemical compound that contains it. In accordance with some example embodiments, the properties of the starting substrate may be modified to obtain a new functionalized substrate. The new substrate may have various applications, such as, for example, an optical- and/or fluorescent-type chemical sensor, as a chemical sequestrator, or as a modifier of the properties of a surface, making it, for example, superhydrophobic. | 05-27-2010 |
| 20090022623 | Peptides Capable of Functioning as Mimotopes for Hormonal Analytes - A purified peptide mimotope which is capable of binding specifically to an antibody specific to estradiol. Also disclosed is an immunoassay test device for the detection in a sample of estradiol, the immunoassay test device comprising a peptide mimotope of estradiol, and an antibody capable of binding specifically to the peptide mimotope to generate a detectable signal. | 01-22-2009 |
