A method and system are provided for the selective use of deconvolution to reduce crosstalk between features of an image. The method to select areas of an image for deconvolution comprising the steps of: a) providing an image comprising a plurality of features, wherein each feature is associated with at least one value (v); b) identifying a test feature which is a high-value feature adjacent to a known low-value zone of the image, wherein the test feature has a tail ratio (rt), which is the ratio of the value of the test feature (vt) to the value of the adjacent low-value zone of the image (vo); c) calculating a threshold value t which is a function of tail ratio (rt) of the test feature; and d) identifying selected areas of the image, the selected areas being those where the ratio of values (v) between adjacent features is greater than said threshold value (T(rt)). Typically, the method of the present invention additionally comprises the step of deconvolving the selected areas of the image.

Abstract:
The present invention provides a detection article including at least one fluid control film layer having at least one microstructured major surface with a plurality of microchannels therein. The microchannels are configured for uninterrupted fluid flow of a fluid sample throughout the article. The film layer includes an acquisition zone for drawing the fluid sample into the plurality of microchannels at least by spontaneous fluid transport. The film layer also includes a detection zone having at least one detection element that facilitates detection of a characteristic of the fluid sample within at least one microchannel of the detection zone. The detection article may be formed from a plurality of film layers that are stacked to form a three-dimensional article.

Abstract:
Devices, methods and systems for low volume microarray processing are disclosed. The microarray devices preferably include a plurality of reactant sites on a reactant surface. The reactant sites include reactants that operate to capture one or more selected analytes that can then be detected based on an electromagnetic signal, e.g., fluorescence, that is emitted by each analyte in response to excitation energy incident on the microarray device. Mixing and/or distribution of the analyte sample over the reactant surface is accomplished by tilting the reactant surface such that the analyte sample flows over the reactant surface under the force of gravity. The tilting is performed such that a portion of the analyte sample accumulates in a bead along a first edge of the reactant surface. The reactant surface is then tilted in a different direction such that a portion of the analyte sample flows over the reactant surface and accumulates at a second edge. The reactant surface preferably generates sufficient capillary forces with the analyte sample such that the analyte sample is retained on the reactant surface. The tilting and resultant flow may be performed as many times as necessary to obtain the desired mixing and/or distribution of analyte sample over the reactant surface.
