Dimpy Gupta 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).

  • Blends of temperature sensitive and anionic polymers for drug delivery
    Patent number: 7767656
    Abstract: A physical blend of inverse thermal gelling and shear-thinning, thixotropic polymers that has a lower gelation temperature than the thermal gelling polymer alone is provided. The blend results in an injectable hydrogel that does not flow freely at room temperature, but is injectable due to its shear-thinning properties. The thermal-gelling properties of the polymer promote a more mechanically stable gel at body temperature than at room temperature. The polymer matrix gel has inherent therapeutic benefit and can also be used as a drug delivery vehicle for localized release of therapeutic agents.
    Type: Grant
