  • Publication number: 20070281369
    Abstract: Detection systems and methods for detecting target biological analytes within sample material using acousto-mechanical energy generated by a sensor are disclosed. The acousto-mechanical energy may be provided using an acousto-mechanical sensor, e.g., a surface acoustic wave sensor such as, e.g., a shear horizontal surface acoustic wave sensor (e.g., a LSH-SAW sensor). A variety of techniques for modifying the effective mass of the target biological analytes in sample material are disclosed, including fractionating or disassembling the target biological analytes in the sample material (e.g., lysing the target biological analyte), adding a detectable mass to the target biological analyte or enhancing coupling of the target biological analyte (e.g., through the use of magnetic particles), exposing the sample material to a reagent that causes a change in at least detectable physical property in the sample material if the target biological analyte is present (e.g.

  • Publication number: 20070154937
    Abstract: Compounds having two reactive functional groups are described that can be used as a tethering compound to immobilize an amine-containing material to a substrate. The first reactive functional group can be used to provide attachment to a surface of a substrate. The second reactive functional group is a N-sulfonyldicarboximide group that can be reacted with an amine-containing material, particularly a primary aliphatic amine, to form a connector group between the substrate and the amine-containing material. The invention also provides articles and methods for immobilizing amine-containing materials to a substrate.

  • Publication number: 20060139754
    Abstract: A prismatic retroreflective article has a transparent body portion and a layer of internally reflecting cube-corner optical elements having an open air-exposed rear surface at least a portion of which is more hydrophobic, more oleophobic, or both more hydrophobic and more oleophobic than the underlying cube-corner optical element. The article may be made by providing a transparent body portion bearing a layer of internally reflecting open air-exposed cube-corner optical elements; treating or coating at least a portion of the cube-corner elements to make the treated or coated portion more hydrophobic, more oleophobic, or both more hydrophobic and more oleophobic than the underlying cube-corner optical elements; and leaving such treated or coated portion exposed to the open air.
