20080204750 | IMAGE ACQUISITION, PROCESSING, AND DISPLAY - Image data is acquired, processed, and/or displayed in accordance with an embodiment of the present disclosure to display, monitor, and/or demonstrate the progress of an experiment substantially in real-time and with high sensitivity. In one embodiment, at least one time-resolved value of spatially distributed polarization change data is provided and displayed. Advantageously, real-time processing and display of data is provided such that discussion and collaboration about the experiment may occur, time-resolved data is not lost, and resources are not wasted. | 08-28-2008 |
20080207463 | APPARATUS AND METHOD FOR PERFORMING LIGAND BINDING ASSAYS ON MICROARRAYS IN MULTIWELL PLATES - An apparatus and method for real time, label-free imaging and quantitation of binding events at an array of positions are provided. Total internal reflection from a planar side wall of a well of a multiwell plate is used to create an evanescent field in the plane of a pattern of ligands immobilized on the wall. Embodiments include imaging and multiple analyte detection and quantitation of a single wall of a single well as well as the simultaneous imaging and multiple analyte detection and quantitation of a number of wells. | 08-28-2008 |
20090041633 | APPARATUS AND METHOD FOR PERFORMING LIGAND BINDING ASSAYS ON MICROARRAYS IN MULTIWELL PLATES - An apparatus and method for real time, label-free imaging and quantitation of binding events at an array of positions are provided. Total internal reflection from a planar side wall of a well of a multiwell plate is used to create an evanescent field in the plane of a pattern of ligands immobilized on the wall. Embodiments include imaging and multiple analyte detection and quantitation of a single wall of a single well as well as the simultaneous imaging and multiple analyte detection and quantitation of a number of wells. | 02-12-2009 |
20090290157 | APPARATUS AND METHOD FOR PERFORMING LIGAND BINDING ASSAYS ON MICROARRAYS IN MULTIWELL PLATES - Ellipsometry systems for imaging binding events between analytes in a sample and an array of ligands in an evanescent field generated by a beam of light reflected from the plane of the ligands is adapted to a multiwell plate structure in common use. In one example, a film of prism arrays is affixed to the underside of the plate with each prism array located in registry with a well and ligand arrays being immobilized on the (planar) bottom surface of the wells. The prism array may be formed in a film and juxtaposed with the bottom surface of the plate or a prism array can be made integral with the plate bottom of a multiwell plate. | 11-26-2009 |
20110157693 | BIOLOGICAL TESTING WITH SAWTOOTH-SHAPED PRISMS - In one embodiment, an apparatus is provided for testing for the presence of analytes in a sample. The apparatus comprises a source of light directed at the bottom surface of a substrate to achieve total internal reflection and to generate an evanescent field. An array of capture elements is immobilized on the top surface of the substrate. The bottom surface of the substrate is configured as a sawtooth (in cross section), the “teeth” aligned with the rows or the columns in the array. The outer faces of the sawtooth “prisms” are non-parallel to the substrate top surface, and specific requirements are imposed on the prism light-entrance face, and the substrate thickness and refractive index. | 06-30-2011 |
