  • Publication number: 20080312532
    Abstract: A system (10, 100, 300, 400) is provided for identifying certain targeted cells or tissues in a body. The system (10, 100, 300, 400) preferably includes at least one ingestible capsule that accommodates or supports (20) at least one of an illuminating module (30, 114, 322, 422, 452), a detecting module (40, 124, 324, 424, 434, 454), an imaging module (50, 326, 432, 456), a control module (60), or a reservoir (70, 132, 312, 412, 442) suitable for retaining and releasing one or more nanoshells. A method (200) is also provided for employing the system (10, 100, 300, 400) to detect, image or otherwise interact with diseased or abnormal cells and/or tissues in a body. The system (10, 100, 300, 400) and method (200) provided allow for improved diagnosing, treating and imaging techniques and for increased sensitivity and specificity in efficiently distinguishing targeted diseased or abnormal cells or tissue from surrounding healthy cells or tissue.

  • Publication number: 20070196239
    Abstract: The present invention relates to the use of the optical properties of nanowires (1) for biomolecule (2) detection. The advantages of using nanowires (1) are a high specific surface area (1a) to bind receptor molecules (3) and size dependent optical properties because of strong quantum confinement of the carriers, i.e. nanowires (1) with different diameters show different colours. The proposed transduction mechanism is based on energy transfer between the biomolecule (2) and the nanowire (1) (or vice versa). Preferably, the target biomolecule (2) is a luminescent biomolecule (2), or said biomolecule (2) is labelled with a dye for quenching of the luminescence of the nanowire (1).

  • Publication number: 20070141736
    Abstract: The invention relates to a field emission device, and a method of manufacturing same. The field emission device comprises a gate electrode (140, 340, 440) which is provided with a pattern of electron passing apertures (135, 335, 435). The gate electrode (140, 340, 440) is arranged near particles (110, 310, 410) distributed on a substrate (125, 325, 425), at least a part of said particles (110, 310, 410) being arranged for emitting electrons. By means of the gate electrode (140, 340, 440), an electric field is applicable by means of which emitting particles emit electrons. Particularly good electron emission is obtained, because the pattern of apertures (135, 335, 435) is similar to the distribution of particles (110, 310, 410) on the substrate. This is achieved by means of the manufacturing method, in which the particles (110, 310, 410) are used in an illumination step to mask regions (155, 355) of a photo layer (150, 352).

  • Publication number: 20060049389
    Abstract: The electric device (1, 100) has a body (2, 101) with a resistor (7, 250) comprising a phase change material being changeable between a first phase and a second phase. The resistor (7, 250) has an electric resistance which depends on whether the phase change material is in the first phase or the second phase. The resistor (7, 250) is able to conduct a current for enabling a transition from the first phase to the second phase. The phase change material is a fast growth material which may be a composition of formula Sb1-cMc with c satisfying 0.05?c?0.61, and M being one or more elements selected from the group of Ge, In, Ag, Ga, Te, Zn and Sn, or a composition of formula SbaTebX100-(a+b) with a, b and 100-(a+b) denoting atomic percentages satisfying 1?a/b?8 and 4?100-(a+b)?22, and X being one or more elements selected from Ge, In, Ag, Ga and Zn.

  • Publication number: 20050244754
    Abstract: A rewritable optical data storage medium (20) for high-speed recording by means of a focused radiation beam (10) is described. The medium (20) comprises a substrate (1) carrying a stack (2) of layers, which stack (2) comprises, a first auxiliary layer (3), a second auxiliary layer (5), and a recording layer (4) of a phase-change material mainly comprising an alloy of Sb and at least one of Ga and In. The recording layer (4) is interposed between the first auxiliary layer (3) and the second auxiliary layer (5). If the alloy is of a composition in atomic percentages defined by the formula: GaxInySbz and 70=z=95 and x+y+z=100 the recording layer (4) has a crystallization speed making it suitable for direct overwrite high speed recording at a velocity of more than 10 m/s and an archival life stability of at least 10 years at 30° C. Further the recording layer (4) has a relatively low media noise.

The medium (20) comprises a substrate (1) carrying a stack (2) of layers. The stack (2) comprises a first dielectric layer (3), a second dielectric layer (5), and a recording layer (4) of a phase-change material of an alloy comprising Sb and Te. The recording layer (4) is interposed between the first dielectric layer (3) and the second dielectric layer (5). The alloy additionally contains 2-10 at. % of Ga, by which a significant improvement of the maximum data rate during direct overwrite is achieved. By furthermore adding 0.5-4.0% of Ge to the alloy the archival life stability is enhanced.
