Jens Tuchscheerer 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: 10753927
    Abstract: A method for assaying a sample for each of multiple analytes is described. The method includes contacting an array of spaced-apart test zones with a liquid sample (e.g., whole blood). The test zones disposed within a channel of a microfluidic device. The channel is defined by at least one flexible wall and a second wall which may or may not be flexible. Each test zone comprising a probe compound specific for a respective target analyte. The microfluidic device is compressed to reduce the thickness of the channel, which is the distance between the inner surfaces of the walls within the channel. The presence of each analyte is determined by optically detecting an interaction at each of multiple test zones for which the distance between the inner surfaces at the corresponding location is reduced. The interaction at each test zone is indicative of the presence in the sample of a target analyte.

  • Patent number: 10365276
    Abstract: The present invention relates to devices and methods for the qualitative and/or quantitative detection of particles. In particular, the invention relates to devices for the detection of particles, comprising a reaction chamber formed within a chamber body between a first surface and a second surface, wherein the second surface is located opposite to the first surface, and one or more displacers, wherein the distance between the first surface and the second surface is variable via the one or more displacers at least in one or more parts of the surface area of the first surface and/or second surface. The invention also relates to corresponding methods for the detection of particles.
