Patents by Inventor Daniel Joh

Daniel Joh 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).

  • Surfaces having reduced non-specific binding and antigenicity
    Patent number: 11752213
    Abstract: Disclosed herein are compositions and methods for reducing the antigenicity of molecules. The antigenicity of a molecule may be reduced or eliminated by conjugating at least one branched polymer to the molecule to form a molecule-polymer conjugate. The branched polymer may include a backbone and a plurality of side chains, each side chain covalently attached to the backbone.
    Type: Grant
    Filed: September 9, 2020
    Date of Patent: September 12, 2023
    Assignee: Duke University
    Inventors: Angus Hucknall, Ashutosh Chilkoti, Daniel Joh, Nancy J. Ganson, Yizhi Qi, Michael S. Hershfield
  • Nonfouling biosensors
    Patent number: 11467156
    Abstract: Disclosed are sensors that include a carbon nanotube channel and a non-fouling polymer layer, where the non-fouling polymer layer and the carbon nanotube channel do not directly contact each other and are separated by a dielectric layer. The disclosed sensors may be used, e.g., as biosensors for the accurate and sensitive detection of analytes within a sample. Also disclosed are methods of making and using the sensors.
