Patents by Inventor Ivan Pushkarsky

Ivan Pushkarsky 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: 11592438
    Abstract: A system for assaying forces applied by cells includes an optically transparent substrate comprising a soft material having a Young's modulus within the range of about 3 kPa to about 100 kPa. An array of molecular patterns is disposed on a surface of the optically transparent substrate, the molecular patterns include fluorophore-conjugated patterns adherent to cells. The system includes at least one light source configured to excite the fluorophore-conjugated patterns and an imaging device configured to capture fluorescent light emitted from the fluorophore-conjugated patterns. Dimensional changes in the size of the patterns are used to determine contractile forces imparted by cells located on the patterns.
    Type: Grant

  • Publication number: 20220187275
    Abstract: An assay for measuring cell-generated forces, is disclosed. The assay includes a first substrate comprising an elastic material having a Young's modulus of between about 0.1 kPa to about 50 kPa and a geometric micropattern disposed onto a surface of the substrate. The micropattern is further comprised of at least one segment consisting of a fluorophore-conjugated material, a material with cell adhesion properties, and has an interior region.
