20140271363 | DIFFRACTION BASED BIOSENSOR CONTAINING TWO DIFFRACTIVE GRATINGS - The present disclosure provides a diffraction based biosensor containing at least two diffraction gratings. The first grating is referred to as an in-coupling diffraction grating and the coherent light source (laser) is directed to illuminate the in-coupling grating, and the biosensor is configured such that a selected order of the light beam diffracted from the in-coupling diffraction grating illuminates a second biosensor grating coated with analyte-specific receptors which are selected to preferentially bind with analytes being tested for that may or may not be located in a sample being tested. | 09-18-2014 |
20130196338 | DETECTION OF BIOMARKERS AND BIOMARKER COMPLEXES - The invention features methods and devices for the detection of biomarker complexes and their components and for the sequential detection of multiple epitopes of a biomarker. The invention also features methods for diagnosing disease and evaluating the efficacy of treatment of a subject with a disease. | 08-01-2013 |
20120015848 | DISPOSABLE REACTION VESSEL WITH INTEGRATED OPTICAL ELEMENTS - The present invention provides disposable, semi-reusable, or single use reaction vessels with integrated optical elements for use with diffraction based assay systems. The vessel for assaying liquids for analytes includes a housing having at least one chamber or well for receiving a liquid therein and an optical element integrally formed with the housing for directing an incident light beam towards the well or chamber and directing a light beam away from the chamber after the light beam has interacted with analytes present in the liquid. The vessel may be test tube such as a blood collection tube, with or without, an optical element but having a pattern of analyte-specific receptors located on an inner surface of the tube wall so that when a liquid is introduced into the interior of the test tube analytes present in the liquid can bind with the pattern of analyte-specific receptors. | 01-19-2012 |
