Jagadeeswaran Chandrasekar 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).

  • Publication number: 20250075265
    Abstract: The invention relates to compounds, methods and compositions for improving on nucleic acid polymerization, including DNA replication by in vitro primer extension to generate, for example, polymers for nanopore-based single molecule sequencing of a DNA template. A nucleic acid polymerase reaction composition is provided with polymerization enhancement moieties, which allows enhanced DNA polymerase activity with nucleotide analogs, resulting in improved length of primer extension products for sequencing applications.

  • Publication number: 20220411458
    Abstract: Phosphoramidate-based monomers are provided for use in the synthesis of expandable polymers for nanopore-based sensing. Such monomers comprising a reporter construct that contain a first reporter code, a symmetrical chemical brancher bearing a translocation control element, and a second reporter code, wherein the ends of the reporter construct are attached to phosphoramidate-nucleoside. Related methods and products are also provided.
