Abstract: The present invention relates to calibration apparatuses, methods or tools used in microscopy. A calibration tool for fluorescent microscopy includes a support, a solid surface layer including a fluorescent material, and a thin opaque mask of non-fluorescent material defining reference feature openings having selected dimensions exposing portions of the surface layer. A first type of the calibration tool may include an adhesion promoter facilitating contact between the surface of the support and the solid surface layer including the fluorescent material, which is in contact with the thin opaque mask. A second type of the calibration tool may include the thin opaque mask fabricated (with or without an adhesion promoter) onto the support, and the solid surface layer including the fluorescent material located on the thin opaque mask.
Abstract: The present invention provides a miniaturized integrated nucleic acid diagnostic device and system. The or more sample acquisition and preparation operations, in combination with one or more sample analysis operations. For example, the device can integrate several or all of the operations involved in sample acquisition and storage, sample preparation and sample analysis, within a single integrated unit. The device is useful in a variety of applications, and most notably, nucleic acid based diagnostic applications and de novo sequencing applications.

Abstract: A data mining tool is described that includes a data structure populator that stores one or more first sets of data selected for querying into a first data structure. The tool also has a query builder that builds at least a first query based, at least in part, on one or more query parameters. Also included in the tool is a query manager that interrogates the first data structure with the first query. The one or more first sets of data are based, at least in part, on experiments using both synthesized probe arrays and spotted probe arrays.
