  • Patent number: 9249050
    Abstract: Substrates, surfaces, assemblies, kits, compositions, and methods are provided for forming touch screens and other appliance surfaces exhibiting good hydrophobicity, oleophobicity, and abrasion resistance. Methods are provided for increasing a population density of hydroxyl groups on a touch surface of a touch screen substrate without affecting the compressive strength of the back surface. The treated touch surface of the substrate can then be coated with a coating that includes an organo-metallic and/or silane, for example, a fluorosilane such as a perfluoropolyether alkoxysilane. A substrate can retain its compressive resistance to breakage by impact applied to the touch surface while minimizing any decrease in compressive strength against impact against the touch surface. Examples of such substrates include touch screens for mobile and desktop electronic devices, components of 3D display devices, and components for electrowetting display devices.

  • Patent number: 8795779
    Abstract: A system and method is shown for coating an article, including a chamber that can be at least partially open to surrounding air to allow free flow of air through the chamber and recovery of vapor produced during a coating operation within the chamber. The chamber can include a support surface that is adapted to support the article during a coating process, and a coating device within the chamber can be adapted to selectively apply a coating of a fluorocarbon in a fluorinated solvent to at least a portion of an article supported on the support surface.

  • Patent number: 8168264
    Abstract: Methods of forming a surface coating are provided. A first component can be applied to a surface and can include at least one adhesion promoter compound. The adhesion promoter compound can include (i) a furfuryl ring structure, (ii) a polymerizable reactive group, and (iii) an alkyloxy moiety linking the furfuryl ring structure to the polymerizable reactive group. A second component can be applied to the surface after the first component is applied to the surface, and the second component can include at least one fluorinated component including from about one to about 100 carbon atoms. The polymerizable reactive group can be polymerized to form a coating on the surface and the first component can improve adhesion of the second component to the surface.

    Abstract: A method comprises loading a sample portion into a sample chamber which comprises means for minimizing diffusion of the sample portion, subjecting the sample portion to an amplification step, and determining whether the sample portion contains at least one molecule of a target nucleic acid. If the sample portion contains a single molecule of the target nucleic acid, the sample portion would attain a detectable concentration of the target nucleic acid after a single round of amplification. Also, a microfluidic device comprising a sample portion and a sample chamber comprising means for minimizing diffusion of the sample portion. Also, a microfluidic device comprising a sample chamber and an amplification targeting reagent positioned in the first sample chamber.
