| 20080299600 | Apparatus Assembly and Method for Detecting an Analyte - An apparatus assembly for detecting an analyte in a sample of material includes a generally self-contained housing and an indicator cap. The housing is moveable between a sample preparation orientation and a testing orientation and is configured to interchangeably receive a sample collection device and the indicator cap having a testing device for detecting the analyte. | 12-04-2008 |
| 20080302193 | Apparatus and Method For Detecting an Analyte - An apparatus assembly for detecting an analyte in a sample of material includes a valve, a frame, and a plurality of housing segments. The valve may be actuated to adjust a flow path and flow rate through the housing segments. | 12-11-2008 |
| 20100129837 | METHODS OF CAPTURING BACTERIAL WHOLE CELLS AND METHODS OF ANALYZING SAMPLES FOR BACTERIA - In certain embodiments, the invention relates to methods of capturing bacterial whole cells that includes the use of two or more antibodies having antigenic specificities for two or more distinct analytes characteristic of the specific bacterium. In certain embodiments, the invention relates to methods of analyzing a sample for a bacterium of interest. In particular, the methods are useful for detecting one or more analytes characteristic of a bacterium of interest, such as components of cell walls that are characteristic of a bacterium, particularly | 05-27-2010 |
| 20100317021 | FLUIDIC ANTIBODY-CONTAINING DEVICES AND METHODS - The invention relates to devices and methods for analyzing a sample (and preferably preparing a sample), which is particularly used in analysis, such as analysis of a sample for a bacterium of interest. | 12-16-2010 |
| 20100330682 | DIACETYLENIC MATERIALS FOR SENSING APPLICATIONS - Diacetylenic materials for the colorimetric detection of an analyte or exposure to certain environmental factors are disclosed as well as the polymerization reaction products of these diacetylenic compounds. | 12-30-2010 |
| 20110028668 | POLYDIACETYLENE POLYMER COMPOSITIONS AND METHODS OF MANUFACTURE - Polyurethane-based polymer compositions that include diacetylene segments are provided. | 02-03-2011 |
| 20110091903 | METHOD OF ANALYZING A SAMPLE FOR A BACTERIUM USING DIACETYLENE-CONTAINING POLYMER SENSOR - The invention relates to methods of analyzing a sample for a bacterium of interest. In particular, the methods involve an initial capture process that includes the use of one or more antibodies having antigenic specificities for one or more distinct analytes characteristic of the specific bacterium. After initial capture of a specific bacterium, techniques of analyzing involve colorimetric techniques, particularly using colorimetric sensors that include polydiacetylene (PDA) materials. | 04-21-2011 |
| 20110097814 | DETECTION DEVICES AND METHODS - The application discloses embodiments of detection devices including a sensor component in a flow path between a first flow path portion and a second flow path portion. In embodiments described, the sensor component includes a receptor in a polymerized composition. The receptor is configured to bind with an analyte in a test sample. Upon binding the sensor component undergoes a detectable change in response to interaction of the analyte with the receptor. | 04-28-2011 |
| 20110146419 | SAMPLE ACQUISITION DEVICE - A sample acquisition device includes a capillary array configured to draw in a sample and retain the sample by capillary action. The capillary array may be coupled to an elongated member, such as a stem or a hollow tube, which defines a longitudinal axis extending in a first direction. In some embodiments, the capillary array defines a major sample acquisition surface that extends in a second direction different than the first direction. A ratio of the major sample acquisition surface area to maximum volume retained by the capillary array may be selected to minimize physical binding between the capillary array and sample. In some embodiments, the device may include a feedback mechanism to indicate the relative pressure applied to a sample source with the sample acquisition device. In addition, in some embodiments, the sample acquisition device may include a suction source to help draw the sample into the capillary array. | 06-23-2011 |
