摘要： A method and apparatus for optically assaying a targeted substance in a sample using a sensor comprising a dielectric film stack having a plurality of dielectric layers. For at least one angle of incidence the dielectric layers operate as a waveguide for light incident upon the sensor. In one configuration, each dielectric layer comprises a dielectric material selected from a first dielectric material having a first index of refraction and a second dielectric material having a second index of refraction. The dielectric film stack is formed such that the dielectric material of the dielectric layers alternates between the first dielectric material and the second dielectric material. The dielectric film stack is either formed as a dielectric mirror such that light incident upon the sensor reflects from the sensor or as an anti-reflection film stack such that light incident upon the light beam propagates through the sensor. The inventive sensor exhibits a resonance that is comparable in magnitude with resonances commonly exhibited by conventional SPR sensors. However, unlike grating-based SPR sensors, the inventive sensor allows a sample to be assayed with substrate-incident light such that the incident light need not propagate through the sample. In addition, because the sensor does not rely on the use of conductive metals, the sensor enables sharp resonances at shorter wavelengths than conventional SPR sensors.

摘要： A thermal transfer donor element is provided which comprises a support, a light-to-heat conversion layer, an interlayer, and a thermal transfer layer. When the above donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. The construction and process of this invention is useful in making colored images including applications such as color proofs and color filter elements.

摘要： Process and materials are described for selectively placing uniform spacers on a receptor. Spacer elements are placed on a receptor by selectively irradiating a thermal transfer donor sheet comprising a transferable spacer layer. The transferable spacer layer may include particles or fibers to form a composite. The particles may have a spacing dimension either greater than or less than the thickness of the transferable layer. When the spacing dimension of the particle is greater than the thickness of the transferable layer, then the spacing dimension of the particles control the spacing distance. The process and materials are useful in the manufacture of flat panel displays, particularly, liquid crystal display devices.
