    摘要: A bright, short wavelength blue-violet phosphor for electroluminescent displays comprises an alkaline-based halide as a host material and a rare earth as a dopant. The host alkaline chloride can be chosen from the group II alkaline elements, particularly strontium chloride (SrCl.sub.2) or calcium chloride (CaCl.sub.2), which, with a europium (Eu) or cerium (Ce) rare earth dopant, electroluminesces at a peak wavelength of 404 and 367 nanometers (nm) respectively. The resulting emissions have CIE chromaticity coordinates which lie at the boundary of the visible range for the human eye thereby allowing a greater range of colors for full color flat panel electroluminescent (FPEL) displays.

    摘要: An analysis device includes an electrode arrangement, a current/voltage provider, and a circuit analyzer. The electrode arrangement has an interdigitated electrode pair including a first electrode and a second electrode. Coupled to the electrode arrangement is a signal generator adapted to provide a signal (e.g., an alternating current or voltage) having a selected range of frequencies. The analyzer is coupled to the electrode arrangement and is operative to analyze an electrical parameter of the circuit as the signal is applied. An analytic method includes measuring changes in one or more parameters of the circuit over the range of frequencies. By such measurement, the device can determine whether a target moiety has been bound by a probe attached to the electrode(s). The device can also specifically identify the intermolecular system detected, i.e., by “finger-printing” the electrical response of each molecule or intermolecular complex.

    摘要: A method for electrochemical impedance spectroscopy uses interdigitated electrodes functionalized with a first species and nanoparticles functionalized with a second species that preferentially attaches to the first species. The nanoparticles are composed of a material with a dielectric constant (k value) greater than 2. The chemically functionalized electrodes are then exposed to a solution containing the chemically functionalized nanoparticles which then become immobilized on the electrodes through the attachment of the first species to the second species. The impedance spectrum is measured and an amount of the first species is then determined from the measured spectrum. Because the high-k dielectric nanoparticles increase the double-layer capacitive impedance, the sensitivity of determining the amount of the first species attached to the second species is enhanced.

    摘要: A biosensor system includes a functionalized interdigitated electrode, functionalized nanoparticles, a current/voltage signal generator, and a circuit analyzer. The interdigitated electrode can be functionalized by coating an exposed surface with first biomolecular probes. The nanoparticles are functionalized by coating an outer surface with second biomolecular probes. A signal generator provides a signal (e.g., an alternating current or voltage) having a selected range of frequencies. A circuit analyzer analyzes electrical parameters of the circuit as the signal is applied. Sensitivity is increased by the presence of functionalized nanoparticles in the system. An analytic method includes measuring changes in electrical parameters of the circuit over the range of frequencies. Using these measurements, the biosensor system can determine whether a target biomolecule is bound. The biosensor system can also identify a biomolecule by comparing the detected signal or “electro-fingerprint” with a reference set of signals over the frequency range.
