20090104635 | Fluorescent Dry Test Strip Biosensor - Disclosed herein is a dry fluorescence biosensor strip for rapid detection of a target analyte present in bodily fluids. The dry fluorescence biosensor strip comprises a sample receptacle and a dry detection membrane. The sample receptacle receives a sample of one of the bodily fluids. The dry detection membrane detects presence of the target analyte in the received sample based on fluorescence induced on the dry detection membrane. Fluorescent signals are emitted from the dry detection membrane on induction of fluorescence. A fluorometer quantifies measurable properties of the target analyte based on the emitted fluorescent signals. The dry fluorescence biosensor strip may further comprise a filtration membrane for filtering the received sample. The filtered sample migrates from the filtration membrane to the dry detection membrane. The dry detection membrane may then detect presence of the target analyte in the filtered sample. | 04-23-2009 |
20090123955 | Size Self-Limiting Compositions and Test Devices for Measuring Analytes in Biological Fluids - A test strip or electrochemical sensor for measuring the amount of an analyte in a hiological fluid, e.g., the glucose content of whole blood, includes a size self-limiting reagent formulation employing an enzyme system for reaction with the analyte, the reactive system mixed into a water-soluble swellable polymer matrix containing small water-insoluble particles having a nominal size of about 0.05 to 20 μm, preferably about 1 to 10 μm. The weight ratio of the water-insoluble particles to the water-soluble swellable polymer matrix is about 1/2 to 2/1. The reagent formulation is deposited onto a non-porous substrate to form a thin layer about 6-16 μm thick, providing a rapid and stable response to application of a sample, while being insensitive to the amount of the sample. | 05-14-2009 |

20110171671 | METHOD FOR DIAGNOSING ACUTE CARDIAC ISCHEMIA - Chemiluminescent detection of metabolic by-products of inosine and hypoxanthine is used to diagnose ischemic events such as early acute cardiac ischemia. | 07-14-2011 |
20120009611 | BIOSENSOR AND BIOSENSOR MANUFACTURING METHOD - A biosensor manufacturing method including a sheet material forming process and a dicing process. In the sheet material forming process a sheet material with plural biosensor forming sections is formed. Each of the biosensor forming sections includes a first base plate, a second base plate stacked on the first base plate and forming a capillary between the second base plate and the leading end portion of the first base plate for sucking in sample liquid, and a hydrophilic layer formed on the second base plate at least in a region facing the capillary. In the dicing process plural biosensors are obtained by dicing the sheet material with a blade from the first base plate side at the leading end of each of the biosensor forming sections, such that the leading end of the capillary opens onto the leading end face of the first base plate and the second base plate. | 01-12-2012 |
20120100563 | Devices and Formulations for Detecting, Screening and Monitoring Levels of Certain Constituents in Bodily Fluids and Method - A device is disclosed for conducting a non-invasive analysis of a bodily fluid to determine the presence and level of a certain constituent carried by the bodily fluid. An indicator formulation of the device changes color in response to exposure to the constituent to provide a visible indication of the presence and level of the constituent carried by the bodily fluid. A carrier substrate of the device is constructed of a material having voids providing a high void volume within the substrate. | 04-26-2012 |
20130023000 | Devices and Formulations for Detecting, Screening and Monitoring Levels of Certain Constituents in Bodily Fluids and Method - A device is disclosed for conducting a non-invasive analysis of a bodily fluid to determine the presence and level of a certain constituent carried by the bodily fluid. An indicator formulation of the device changes color in response to exposure to the constituent to provide a visible indication of the presence and level of the constituent carried by the bodily fluid. A carrier substrate of the device is constructed of a material having voids providing a high void volume within the substrate. The device is made by applying a chromagen to the carrier substrate to create a chromagen-laden carrier member. Then, a selected reagent having a particular constituent-specific formulation is applied to the chromagen-laden member. The selected reagent then combines with the chromagen, thereby establishing the indicator formulation within the carrier substrate in place for reception of a sample of the bodily fluid. | 01-24-2013 |
