Patents by Inventor Roberta Polak

Roberta Polak 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).

  • Synthetically functionalized living cells for targeted drug delivery
    Patent number: 11400114
    Abstract: Uniform, functional polymer patches can be attached to a fraction of the surface area of living individual cells. These surface-modified cells can cross the blood-brain barrier while remaining viable after attachment of the functional patch. Functional payloads carried by the patch can include a drug. The patch can include one or more polyelectrolyte multilayers (PEMs).
    Type: Grant
    Filed: March 14, 2017
    Date of Patent: August 2, 2022
    Assignees: MASSACHUSETTS INSTITUTE OF TECHNOLOGY, THE UNIVERSITY OF NORTH CAROLINA AT CHAPEL HILL
    Inventors: Roberta Polak, Robert E. Cohen, Michael F. Rubner, Elena V. Batrakova, Matthew J. Haney, Natalia L. Klyachko, Yuling Zhao
  • Spray-coating method with particle alignment control
    Patent number: 11149154
    Abstract: A simple spray coating process can be utilized to create epoxy/HNT nanocomposites with vertically aligned nanotubes. Important mechanical properties such as modulus and hardness values can be optimized and enhanced by controlling the level of nanotube dispersion during processing and the final orientation of the nanotubes. Thus, a technologically relevant processing scheme can be used to fabricate HNT nanocomposites with a high level of control over nanotube alignment and the resulting mechanical properties.
