Patents by Inventor Suman Sen

Suman Sen 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: 20210389296
    Abstract: The present disclosure provides apparatus and methods for determining the sequence of a nucleic acid. The apparatus comprises electrodes that form a tunnel gap through which the nucleic acid can pass. The electrodes comprise a reagent that is capable of selectively interacting with a nucleobase of the nucleic acid sequence. When the reagent interacts with a nucleobase, a detectable signal is produced and used to identify the nucleobase of the nucleic acid. Advantageously, the apparatus of this disclosure is specific to identifying nucleic acids.

  • Patent number: 10336713
    Abstract: Triazole-based molecules, methods of making and using the same are provided. Triazole-based molecules may be used as reading molecules and incorporated into or operatively-linked with electrodes, for example, and used in recognition tunneling systems to identify individual and/or sequences of molecules (e.g., DNA bases, carbohydrates, proteins, peptides, and/or amino-acids).

  • Patent number: 10072036
    Abstract: The invention relates to an N-heterocyclic carbene complex of general formulas I to IV (I) (II) (III) (IV), according to which A1 stands for NR2 or PR2, A2 stands for CR2 R2?, NR2, PR2, 0 or S, A3 stands for N or P, and C stands for a carbene carbon atom, ring B is an unsubstituted or a mono or poly-substituted 5 to 7-membered ring, substituents R2 and R2? stand, inter alia, for a linear or branched C1-Cw-alkyl group and, if N and N each stand for NR2 or PR2, are the same or different, M in formulas I, II, III or IV stands for Cr, Mo or W, X 1 or X2 in formulas I to IV are the same or different and represent, inter alia, C1-C1s carboxylates and C1-C1s-alkoxides, Y is inter alia oxygen or sulphur, Z is inter alia a linear or branched C1-Cw-alkylenoxy group, and R 1 and R1? in formulas I to IV are, inter alia, an aliphatic or aromatic group.
