Patents by Inventor Shufang Ci

Shufang Ci 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: 20200063197
    Abstract: The present disclosure relates to real-time quantification using loop-mediated isothermal amplification, in particular real-time colorimetric reverse transcription quantitative loop-mediated isothermal amplification (RT-qLAMP). In some embodiments, RT-qLAMP is used to diagnose the presence of and also quantitate the amount of Zika virus in a sample.

  • Patent number: 10471426
    Abstract: The invention relates to microfluidic devices and array disks for “one-pot” isolated chemical reactions. The array disks comprise a plurality of sectors in which each sector comprises one microfluidic device. The microfluidic devices comprise a fluid delivery channel and an array of wells wherein the fluid delivery channel delivery fluid into the wells in a serpentine arrangement. In some embodiments, the fluid delivery channel is directly above the array of wells. In other embodiments, the fluid delivery channel is offset from the array of wells so that side channels branching from the fluid delivery channel delivers fluid into the wells. The well of the microfluidic device comprises a gas-permeable membrane that forms the floor, well, or at least a portion of the floor or wall of the well. In preferred embodiments, the well is cylindrical.

  • Patent number: 10260090
    Abstract: A method of synthesizing a nucleic acid complementary to a target nucleic acid sequence in a template nucleic acid includes annealing a swarm primer to a target nucleic acid, the swarm primer overlapping an F1 site of the target nucleic acid and extends toward the F2 site of the target nucleic acid. An inner primer may also be annealed to the target nucleic acid to produce a complimentary nucleic acid having a single-strand loop onto which further primers may anneal. A plurality of amplicons may be reproduced, many of which may have further primers annealed thereto to generate more complementary nucleic acids.
