Abstract:
The invention relates to a synthesis device, especially for use in combinatorial chemistry (for example solid-phase synthesis), and to a method for producing the same. The inventive synthesis device substantially comprises a container, such as for example a microtiter plate, having wall and/or bottom areas, and a solid-phase support, for example membranes that are suitable for use in solid-phase synthesis. The support is fixed to at least one of the container areas by thermally influencing an area of the solid-phase support, preferably a clearly defined area.
Abstract:
Arrays including microparticles having probe moieties are used for the detection of a target in a sample. Microparticles (104) are immobilized in a polymer matrix (106) and form clustered arrangements (108) on at least a portion of a substrate (102). A detection scheme is performed to detect a marker associated with the target which can be bound to a probe of a clustered arrangement (108).
Abstract:
The present invention overcomes the problems and disadvantages associated with prior art arrays by providing an array comprising a plurality of biological membrane microspots associated with a surface of a substrate that can be produced, used and stored, not in an aqueous environment, but in an environment exposed to air under ambient or controlled humidities. Preferably, the biological membrane microspots comprise a membrane bound protein. Most preferably, the membrane bound protein is a G-protein coupled receptor, an ion channel, a receptor serine/threonine kinase or a receptor tyrosine kinase.
Abstract:
A "process of elimination" method of creating mixtures of labeled particles, allowing the particles to interact, documenting particle interactions or lack thereof, and collating information derived from more than one experiment, with each experiment combining particles from one or more mixtures with other particles.
Abstract:
The present invention is an apparatus for providing a linear temperature gradient to an architecture suitable for massively parallel chemical or biochemical processing. The architecture is disposed on a substrate. The apparatus uses two temperature elements disposed essentially parallel to each other and in thermal contact with the substrate. When the temperature elements are held at different temperatures, a linear temperature gradient is formed in the substrate.
Abstract:
A carrier for gene detection as a means for prediction before treatment whether interferon therapy is valid or not for a patient, a method for detection of interferon therapy for an individual, an apparatus for gene detection, and a kit for detection of validity of interferon therapy.
Abstract:
Fluidic methods and devices for conducting parallel chemical reactions are disclosed. The methods are based on the use of in situ photogenerated reagents such as photogenerated acids, photogenerated bases, or any other suitable chemical compounds that produce active reagents upon light radiation. The present invention describes devices and methods for performing a large number of parallel chemical reactions without the use of a large number of valves, pumps, and other complicated fluidic components. The present invention provides microfluidic devices that contain a plurality of microscopic vessels for carrying out discrete chemical reactions. Other applications may include the preparation of microarrays of DNA and RNA oligonucleotides, peptides, oligosacchrides, phospholipids and other biopolymers on a substrate surface for assessing gene sequence information, screening for biological and chemical activities, identifying intermolecular complex formation, and determining structural features of molecular complexes.
Abstract:
A substrate having a surface with reversibly switchable properties. The surface comprises a nanolayer of a material that switches from a first conformation stateto a second conformation state when an external stimulus is applied. When the nanolayer is in the first conformation state, the surface is characterized by a first property, and when the nanolayer is in the second conformation state, the surface is characterized by a second property.
Abstract:
Method and apparatus for mixing small volumes of reaction components. In one application, a plurality of removable vessels (5) are placed in a parallel reactor, and reaction components are delivered to each vessel. An impeller (3) is rotated in each vessel to mix the components. Each impeller (3) has a rotary shaft (25) and at least one blade (2+) on the shaft for placement in the reaction components. The blade is dimensioned so that one rotation of the impeller (3) causes the blade (2+) to sweep out a sweep volume representing a large amount of the fill volume (FL) of the vessel (5).
Abstract:
This invention provides an apparatus and method for dispensing fluidic materials involving the employment of a hydrophilic capillary (24) dimensioned for drawing a liquid therein in a volume less than about 10 microliters; a hydrophobic medium (26) sealingly adjoining said capillary (24) and defining an interface (22) therewith for resisting flow of the liquid into the capillary beyond the interface; and a source of a pressure pulse for ejecting fluids drawn into the capillary (24).
