摘要： An OLED includes a wide gap inert host material (40) doped with two dopants. One of the dopants is an emissive phosphorescent material that can transport either electrons or holes. The other dopant is a charge carrying material that can transport whichever of the electrons and holes that is not transported by the phosphorescent dopant. The materials are selected so that the lowest triplet energy level of the host material and the lowest triplet energy level of the charge carrying dopant material are each at a higher energy level than the lowest triplet state energy level of the phosphorescent dopant material. The device is capable, in particular, of efficiently emitting light in the blue region of the visible spectrum.

摘要： The present invention relates to microfluidic and nanofluidic devices for detecting or measuring an electrical property of a fluid including a liquid or aerosol, a single molecule or a single particle or cell in a fluid. In a particular embodiment, the devices detect or measure changes in capacitance of a fluid, molecule, particle or cell as it passes through the device. The present invention also relates to the detection and measurement of single molecules, in particular, biological molecules. The present invention also relates to methods of sequencing polynucleotide molecules, such as RNA or DNA, by detecting differentially labeled single nucleotides. Applications of this technology of single molecule detection, includes DNA or RNA sequencing which require a resolution of 3-5 nucleotides, detection of SNPs which require a single nucleotide resolution, protoemics which require 3 nucleotide resolution, and particle sizing. The microfluidic device can be used to determine the DNA content of cell, to analyze cell-cycles kinetics of populations of cells and as an assay for abnormal changes in DNA content of cells. The nano-microfluidic devices of this inveniton also have utility for use as detectors in molecular sorting systems and detecting of pathogens and spores. The present invention is also referred to as 'Capacitance cytometry'.

摘要： Methods and apparatus for sorting microstructures, such as macromolecules, viruses, cells, and minute particles, in a fluid and for hermetically and reversibly sealing a microlithographic sorting array. A silicone elastomer cover is used in one embodiment. In another, silicon microstructures are used to cast elastomeric replicas of obstacle arrays, the tops of which reversibly seal against a flat surface. The reversible seal allows access to fractionated cells within the structure for further analysis.

摘要： The present invention relates to a method and apparatus for hyperpolarizing a noble gas by spin-exchange optical pumping which includes a polarization cell containing the noble gas, a primary alkali metal and an auxiliary alkali metal. The polarization cell is illuminated with radiation to optically polarize the primary alkali metal. This enables spin-exchange interaction between the primary alkali metal, the auxiliary alkali metal and the noble gas resulting in a hyperpolarized noble gas.

摘要： The methods of this invention involve modification of an organic film after it has been deposited by either adding new dopants into it from top or bottom surface, or by causing dopants to leave the film from its top or bottom surface. In the examples of these methods, the emitting color of light emitting diodes are modifed based on doped polymers by locally introducing dopants causing different color emission into the film by local application of a solution containing desired dopant to the film surface (by ink-jet priniting, screen printing, local droplet application, etc.). This covers the difficulties of encountered with direct patterning of three separately formed organic layers (each which uniformely coats an entire surface when formed) into regions for separate R, G, and B devices due to sensitivities of the organic materials to chemicals typically used with conventional patterning technologies. Alternatively, dopants may be introduced in an organic film (16) by diffusion from one layer (18, 19) into the film (16). Alternatively, dopants may be selectively removed form a film with solvents, etc.

摘要： A method of fabricating semiconductor devices using ink-jet printing is provided to directly deposit patterned polymer films (136) to create OLED's and other semiconductor devices. The luminescence of poly-vinylcarbazol (PVK) films, with dyes of coumarin 6 (C6), coumarin 47 (C47), and nile red was similar to that of films of the same composition deposited by spin-coating. Light emitting diodes with low turn-on voltages were also fabricated in PVK doped with C6 deposited by ink-jet printing.

摘要： A method of imaging a spatial distribution of a noble gas by nuclear magnetic resonance spectrometry includes detecting a spatial distribution of at least one noble gas by NMR spectrometry and generating a representation of said spatial distribution of the noble gas. The noble gas is selected from noble gas isotopes having nuclear spin, preferably Xenon-129 and/or Helium-3. The noble gas is at least thermally or equilibrium polarized and is preferably hyperpolarized, most preferably hyperpolarized by optical (laser) pumping in the presence of an alkali metal or by metastability exchange. The generation of the representation of the noble gas spatial distribution includes at least one dimension, preferably 2 or 3 dimensions of the spatial distribution. The noble gas may be imaged according to the invention in chemical or biological systems, preferably in a human or animal subject or organ system or tissue thereof. Also, apparatus for nuclear magnetic resonance imaging of the spatial distribution of at least one noble gas includes means for imaging a noble gas by NMR spectrometry and means for providing and/or storing imageable quantities of a noble gas, preferably hyperpolarized Xenon-129 and/or Helium-3. Also, a medical composition includes a medically acceptable bifunctional gas effective for in vivo anesthesiological and NMR imaging functions, including at least one noble gas, preferably hyperpolarized Xenon-129 and/or Helium-3.
