  • Patent number: 6664060
    Abstract: The present invention provides high-density arrays including mask layers and methods of manufacturing the same. The arrays are formed on a polymeric substrate and include a mask layer. Various linking agents, linking agent coatings, and/or reactants may be provided on the mask layer. Where present, the linking agents and reactants preferably operate together to capture a desired analyte which can then be detected based on an electromagnetic signal, e.g., fluorescence, that is emitted by the analyte in response to excitation energy incident on the array. With the mask layer in place, the signal-to-background ratio provided by the arrays can be increased.

  • Publication number: 20030036090
    Abstract: Articles, such as high density arrays, on heat-relaxable substrates that can be relaxed by exposure to thermal energy are disclosed, along with methods of manufacturing the arrays, and systems/apparatus for relaxing arrays using electromagnetic energy. The arrays may themselves include electromagnetic energy sensitive material in their construction, in which case exposure of the arrays to suitable electromagnetic energy can provide the thermal energy required to cause the arrays to relax. In other embodiments, the arrays may not include an electromagnetic energy sensitive material in their construction, in which case the arrays may be heated indirectly, i.e., by locating the arrays within a system or apparatus that includes an electromagnetic energy sensitive material and transferring the thermal energy from the electromagnetic energy sensitive material to the array by, e.g., conduction.
