摘要:
The present invention relates to a method of encoding and decoding of a microarray which is used for detecting the presence of one or more target analytes in a sample. Further disclosed are microarrays produced according to these methods and their use.
摘要:
A microfluidic assay device that defines a micro-fluidic flow channel (44) having a flow axis, in which a series of discrete, axially-spaced apart, transparent hollow flow elements (32) are secured in fixed position, each flow element having at least one axially-extending flow passage through its interior, assay capture agent fixed to the interior surface of the elements for capture of an analyte in liquid flowing through the interior of the flow elements, the device constructed to enable light to be transmitted out of the elements for reading of fluorescence from captured analyte, wherein: the exterior axially-extending surfaces of the flow elements are free of active capture agent, while at least part of the interior surfaces carry deposits of active capture agent exposed to flow through the elements.
摘要:
A pneumatically driven portable assay cartridge having analyte capture regions associated with microfluidic channels within its interior, the portable cartridge having pneumatic ports clampable against pneumatic ports of an operating instrument for controlled application of positive pressure and vacuum to pneumatic operating channels within the cartridge, the cartridge having a well for receiving sample from a user and microfluidic channels that include pneumatically operated pistons and valves controllable by the pneumatic operating channels to cause all flows of the assay from the reservoirs through reaction regions within the cartridge to on-board waste reservoir during conduct of the assay.
摘要:
The invention concerns a particle (10, 10a) having a code from a library of codes embedded in its physical structure by refractive index changes between different regions of the particle. In preferred embodiments, a thin film possesses porosity that varies in a manner to produce a code detectable in the reflectivity spectrum. An assay detection method uses such a particle and detects a spectral shift in the presence of an analyte. Additional embodiments are disclosed including additional features.
摘要:
Methods and compositions for encoding and decoding array information on an array are provided. The methods involve contacting an array containing one or more array information features with a sample containing target that binds to at least one of the one or more array information features to produce at least one signal that provides information about the array.

摘要:
The present invention provides a microarray for multiple sample analysis that does not require a alignment of well walls with corresponding probe sets. Methods for building and using such a microarray are also within the scope of the present invention.
摘要:
It is intended to omit a constitution with a need for absolute accuracy in an examination apparatus equipped with a DNA substrate on which a plural number of DNA fragments to be examined are located. This object can be achieved by providing a substrate having a plural number of biomolecular spots comprising a mass of biomolecules (DNA, etc.) of a specific type wherein the pattern or location of the DNA spots can be altered depending on specific data and thus the specific data can be recorded.
摘要:
The invention provides an apparatus for chemical synthesis comprising a light source, for example, a laser light source; a means for dispensing a chemical reagent onto the solid support; a means for splitting light emanating from the light source into two or more split beams of light; a means for polarizing the beams of light; a means for collimating the polarized light; a 1/4-wave plate disposed between the collimating means and the solid support; a means for focusing the polarized light onto the solid support; and a photodetector array.
摘要:
The process of the invention permits the synthesis of large libraries of materials of multicomponent systems, in which all mixtures of binary to polynary systems are synthesized rapidly and arbitrarily in the multicomponent system. Combining an inventive library of materials with an inventive test for performance characteristic extremely accelerates the screening of a large number of novel materials.
