Abstract: A microfluidic device is described herein which comprises a micron-sized deep flow channel and a sensor. The micron-sized deep flow channel is configured such that a sample solution and a reference solution flow side-by-side to one another in a single sensing region of the sensor. The single sensing region is divided into a detection region and a reference region which are contiguous to one another and which are respectively interfaced with the sample solution and the reference solution that flow side-by-side to one another in a longitudinal direction within the micron-sized deep flow channel.

Abstract: A sealing method for decreasing the time it takes to hermetically seal a device and the resulting hermetically sealed device (e.g., a hermetically sealed OLED device) are described herein. The sealing method includes the steps of: (1) cooling an un-encapsulated device; (2) depositing a sealing material over at least a portion of the cooled device to form an encapsulated device; and (3) heat treating the encapsulated device to form a hermetically sealed device. In one embodiment, the sealing material is a low liquidus temperature inorganic (LLT) material such as, for example, tin-fluorophosphate glass, tungsten-doped tin fluorophosphate glass, chalcogenide glass, tellurite glass, borate glass and phosphate glass. In another embodiment, the sealing material is a Sn2+-containing inorganic oxide material such as, for example, SnO, SnO+P2O5 and SnO+BPO4.

Abstract: A method for producing glass or glass ceramic articles by powder injection molding of glass powder includes mixing together, in a continuous mixing process, ingredients to form a mixture comprising a glass powder and a binder, where the ingredients include a glass powder in a relative amount sufficient to equal at least 50% by volume of the resulting mixture and a binder comprising a thermoplastic polymer, desirably a thermoplastic elastomer, and a wax; forming the mixture into a formed structure; and de-binding and sintering the formed structure. The method desirably involves mixing via a high intensity mixing process, desirably by mixing in a twin-screw extruder. The forming process may include pelletizing the mixture and injection molding the pelletized mixture to form the formed structure. The ingredients of the mixture desirably comprise a glass powder in a relative amount sufficient to equal at least 70% by volume of the resulting mixture.

Abstract: A method for inhibiting oxygen and moisture degradation of a device and the resulting device are described herein. To inhibit the oxygen and moisture degradation of the device, a low liquidus temperature (LLT) material which typically has a low liquidus temperature (or in specific embodiments a low glass transition temperature) is used to form a barrier layer on the device. The LLT material can be, for example, tin fluorophosphate glass, chalcogenide glass, tellurite glass and borate glass. The LLT material can be deposited onto the device by, for example, sputtering, evaporation, laser-ablation, spraying, pouring, frit-deposition, vapor-deposition, dip-coating, painting or rolling, spin-coating or any combination thereof. Defects in the LLT material from the deposition step can be removed by a consolidation step (heat treatment), to produce a pore-free, gas and moisture impenetrable protective coating on the device. Although many of the deposition methods are possible with common glasses (i.e.

The bend is constructed such that the width and either the inside radius of curvature, the outside radius of curvature or both change simultaneously.

Abstract: An assembly to practice a method for the detection and analysis of genetic polymorphisms using arrays that do not require labeling of a target nucleic acid sequence. Hybridization of a perfectly complementary nucleic acid target sequence to an oligonucleotide probe sequence results in a displacement and complete removal of a hybridized probe sequence from the same oligonucleotide probe sequence by means of a thermo-kinetic reaction. The removal of the hybridized probe sequence, having a quencher element, increases the intensity of emission by an emitter element on the oligonucleotide probe sequence.

There are disclosed two embodiments of the electrophoretic inorganic porous material including a porous glass and a sol gel monolith.

Abstract: Disclosed is a method for the introduction of unidirectional deletions in a cloned DNA segment in the context of a cloning vector which contains an f1 endonuclease recognition sequence adjacent to the insertion site of the DNA segment. Also disclosed is a method for producing single-stranded DNA probes utilizing the same cloning vector. An optimal vector, PZIP is described. Methods for introducing unidirectional deletions into a terminal location of a cloned DNA sequence which is inserted into the vector of the present invention are also disclosed. These methods are useful for introducing deletions into either or both ends of a cloned DNA insert, for high throughput sequencing of any DNA of interest.

Abstract: Disclosed is a method for the introduction of unidirectional deletions in a cloned DNA segment. More specifically, the method comprises providing a recombinant DNA construct comprising a DNA segment of interest inserted in a cloning vector, the cloning vector having an f1 endonuclease recognition sequence adjacent to the insertion site of the DNA segment of interest. The recombinant DNA construct is then contacted with the protein pII encoded by gene II of phage f1 thereby generating a single-stranded nick. The nicked DNA is then contacted with E. coli Exonuclease III thereby expanding the single-stranded nick into a single-stranded gap. The single-stranded gapped DNA is then contacted with a single-strand-specific endonuclease thereby producing a linearized DNA molecule containing a double-stranded deletion corresponding in size to the single-stranded gap. The DNA treated in this manner is then incubated with DNA ligase under conditions appropriate for ligation.
