Patents by Inventor Akhilesh K. Gaharwar

Akhilesh K. Gaharwar 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).

  • Patent number: 11414556
    Abstract: A biodegradable and biocompatible three dimensional construct comprising a combination of a nano silicate (e.g., laponite) and two different polymers, the two polymers each individually providing at least one covalently linked polymer chain and at least one ionically linked polymer chain, the polymeric chains forming a dual strengthening intertwined polymeric system. The constructs demonstrate improved mechanical and strength properties, while the bioinks provide a material having superior printability characteristics suitable for printing a three dimensional biodegradable construct having an aspect ratio of greater than 2.0. The bioink may also comprise cells or combinations of cells. Methods of using the constructs and bioinks for wound healing preparations and tissue regeneration are also provided.
    Type: Grant
    Filed: March 13, 2018
    Date of Patent: August 16, 2022
    Assignee: THE TEXAS A&M UNIVERSITY SYSTEM
    Inventors: Akhilesh K. Gaharwar, David Chimene
  • Patent number: 10898445
    Abstract: Aspects of the invention are directed to mineral-based nanoparticles comprising silicate nanoparticles that induce human mesenchymal stem cells (hMSCs) into a cartilage-lineage through the upregulation of cartilage-specific genes resulting in the transformation of the cell phenotype into that of a chondrocyte, i.e., a cartilage producing cell. The silicate nanoparticles are synthesized through a process where the precipitate of sodium silicate is mixed with one or more elements and compounds and milled into nanoparticles.
