More specifically this invention relates to capture layer assemblies for cellular assays using optical bio-discs. The current invention includes methods for determining the quality and quantity of a specific type of cell in a biological sample. These methods includes binding capture agents to a capture zone on the disc, providing a sample to the capture zone, remove portions of the sample that are not bound in the capture zone, and counting bound cells. The current invention also includes methods and apparatus for performing a cluster designation marker assay using an optical disc and disc drive and method for making optical analysis discs for performing such cluster designation assays.
Abstract:
The invention provides a method and apparatus for non-destructive testing of bonded structures, such as laminated or composite materials. A beam of coherent light is directed successively onto each point of the object. The reflected beam creates a speckle pattern. The pattern is observed once while the object is stationary and once while the object is mechanically excited. If the point being observed is free of defects, the speckle pattern will be substantially unaffected by the vibration of the excited object. If the point is defective, vibration will blur the speckle pattern. The entire object is scanned, point by point, and the results of the comparison of the speckle patterns obtained for each point are stored and displayed. In another embodiment, the object is made to vibrate continuously, and the apparatus determines whether the speckle pattern is sharp or blurred, for each point being scanned. The sharpness of the speckle pattern can be inferred from the measured intensity of the speckle pattern, or it can be calculated directly by a suitable algorithm. In general, if the detector has a nonlinear response characteristic, the total intensity of the speckle pattern will be lower when the pattern is blurred, and higher when the pattern is sharp. A low intensity therefore indicates that the point on the object is defective. As in the first embodiment, the results of the analysis are stored in a computer memory and displayed on a video monitor.

A scanning illuminating device includes an emission center from which radiation is emitted in an illuminating sector. A cylindrical ring is centered on the source and is rotatably movable about a first axis.

Abstract:
Analyzers and analyzer systems that include an analyzer for determining multiple label species, methods of using the analyzer and analyzer systems to analyze samples, are disclosed herein. The analyzer includes one or more sources of electromagnetic radiation to provide electromagnetic radiation at wavelengths within the excitation bands of one or more fluorophore species to an interrogation space that is translated through the sample to detect the presence or absence of molecules of different target analytes. The analyzer may also include one or more detectors configured to detect electromagnetic radiation emitted from the one or more fluorophore species. The analyzer for determining multiple target molecule species provided herein is useful for diagnostics because the concentration of multiple species of target molecules may be determined in a single sample and with a single system.
