Abstract:
The invention concerns a particle 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.
Abstract:
In a multiplexed assay, each molecule of a plurality of molecules is attached to a support matrix particle with a substrate adapted for attachment and/or synthesis of molecules. A spectrally-encoded identifier embodied in a photochemical medium is embedded or encased within the substrate to uniquely identify the molecule attached to the substrate. The molecules are exposed to one or more processing conditions, and then placed within the path of an optical detector adapted to read the spectrally-encoded identifier and measure biochemical activity on each support matrix particle. The measured biochemical activity is associated with the unique identity of the support matrix particle and, hence, with the molecule attached to the particle.

Combinations, called matrices with memories, of matrix materials with remotely addressable or remotely programmable recording devices that contain at least one data storage unit are provided. The matrix materials are those that are used in as supports in solid phase chemical and biochemical syntheses, immunoassays and hybridization reactions. The matrix materials may additionally include fluophors or other luminescent moieties to produce luminescing matrices with memories. The data storage units are non-volatile antifuse memories or volatile memories, such as EEPROMS, DRAMS or flash memory. By virtue of this combination, molecules and biological particles, such as phage and viral particles and cells, that are in proximity or in physical contact with the matrix combination can be labeled by programming the memory with identifying information and can be identified by retrieving the stored information. Combinations of matrix materials, memories, and linked molecules and biological materials are also provided. The combinations have a multiplicity of applications, including combinatorial chemistry, isolation and purification of target macromolecules, capture and detection of macromolecules for analytical purposes, selective removal of contaminants, enzymatic catalysis, cell sorting, drug delivery, chemical modification and other uses. Methods for electronically tagging molecules, biological particles and matrix support materials, immunoassays, receptor binding assays, scintillation proximity assays, non-radioactive proximity assays, and other methods are also provided.

Abstract:
The invention relates to a recognizable carrier for determining physical, chemical or biochemical interactions by means of optical measurement methods. The carrier comprises a surface that defines a substrate surface and that has a base layer coated with reactive elements, which are bonded to receptor molecules, wherein the base layer and/or the reactive elements are provided with a pattern of holes which forms a code and/or the reactive elements are provided with linker molecules or markers which form a code. The substrate surface may additionally have a macroscopically planar pattern which is applied using laser light or chemical etching and forms a code. The invention likewise relates to a method for producing a recognizable carrier for spectroscopic processes and/or intensiometric tests to determine said interactions. The code to recognize the carrier can be controlled via a read-out unit coupled to the photometric analysis unit. Such a carrier can be used to analyze biomolecules during security checks, access controls or in-vitro diagnostics.
