  • Electrospun nanofibers
    Patent number: 11932970
    Abstract: A nanofiber comprising a polyamide including at least one substituted phenyl group is provided. The nanofiber includes an average diameter from about 50 to about 1000 nm. A fibrous mat including a plurality of the nanofibers is also provided. A composite including a plurality of the nanofibers and a continuous matrix resin is also provided. A method of forming the nanofibers is also provided.
    Type: Grant
    Filed: August 28, 2019
    Date of Patent: March 19, 2024
    Inventors: Christopher M. Hoffman, Jr., Matthew P. Yeager, Morgana M. Trexler, Zhiyong Xia, Douglas A. Smith, Marcia W. Patchan
  • Electrospinning aramid nanofibers
    Patent number: 10801131
    Abstract: Example methods and articles of manufacture related to electrospun aramid nanofibers are provided. One example method may include forming a resultant solution by reacting a solution of aramids dissolved in a solvent with an electrophile. In this regard, the electrophile may perform a side chain substitution on the dissolved aramids. The example method may further include electrospinning the resultant solution to form an aramid nanofiber.

  • Capacitive liquid crystal biosensors
    Patent number: 10344320
    Abstract: A capacitive liquid crystal (LC) biosensor for sensing a target biological agent includes a support board; a flow channel on the support board, the flow channel having an inlet port at a first end and an exit port at a second end; at least two electrodes, the at least two electrodes including a first electrode on a flow channel first surface and a second electrode on a flow channel second surface opposite the flow channel first surface; an electricity source connected to the first electrode and the second electrode; and an LC sensor array positioned within the flow channel. An LC sensor array includes a sensor support surface; wells positioned on the sensor support surface; an organic LC phase within each of the plurality of wells; and an aqueous phase having an analyte positioned above the organic LC phase within the wells.
