Heinz Koehn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8580499
    Abstract: The present invention relates to a method and device for detecting and/or quantifying one or multiple target molecules present in a solution by quantifying online their binding on specific capture molecules immobilized at different locations (spots) of a surface of an optically transparent solid support without substantial detection of target molecules present in solution. The present invention allows multiple target assays to be performed in a simultaneous detection. More particularly, the invention comprises detecting in real-time the hybridization between capture DNA molecules present on a micro-array and target polynucleotides present in solution. The invention is also related to real-time PCR of multiple targets on a micro-array.

  • Patent number: 7875442
    Abstract: Disclosed is a system and method conducting real-time PCR. Unlabeled capture molecules of a specific design are immobilized on a solid support, and contacted with amplicons produced in one or more PCR cycles. Detection of amplicons may take place during or between the PCR cycles while the solid support is in fluidic contact with the PCR solution. In an alternate embodiment detection of the amplicons takes place when the solid support is not in fluidic contact with the PCR solution. The method is suitable for the simultaneous detection and quantification of closely homologous target molecules.

  • Publication number: 20090163377
    Abstract: The invention relates a method for detecting and/or quantifying different target molecules being bound at different locations (spots) of a surface of an optically transparent solid support having a refractive index n1 by specific interaction with capture molecules being immobilized on the solid support surface, said solid support being in contact with a solution having refractive index n2, whereby n1>n2 and wherein the target molecules are in contact with the capture molecules, said method comprising the steps of: a) illuminating homogeneously the surface of the support on which the target molecules are bound, thereby causing homogeneous excitation of the target molecule; b) detecting light emitted from the target molecules in at least four different locations (spots) in the following way: collecting the emitted light through a side of said support which is inclined relative to the surface of the support on which the target molecules are bound, focusing the emitted light by a lens on a detector surface
