  • Patent number: 11642849
    Abstract: Bio-Inks and methods of using compositions comprising the bio-Inks are disclosed. 3-D tissue repair and regeneration through precise and specific formation of biodegradable tissue scaffolds in a tissue site using the bio-inks are also provided. Specific methylacrylated gelatin hydrogels (MAC) and methacrylated chitosan (MACh) preparations formulated with sucrose, a silicate-containing component (such as laponite), and/or a cross-linking agent (such as a photo-initiator or chemical initiator), as well as powdered preparations of these, are also disclosed. Kits containing these preparations are provided for point-of-care tissue repair in vivo. Superior, more complete (up to 99.85% tissue regeneration within 4 weeks applied in situ), and rapid in situ tissue repair and bone formation are also demonstrated.

  • Patent number: 10569067
    Abstract: A controlled release nanoparticulate matter delivery system includes a plurality of thermoresponsive modules containing a respective nanoparticulate matter. Each thermoresponsive module is selectively operable in at least one of a heating mode that releases the nanoparticulate matter and a cooling mode that inhibits release of the nanoparticulate matter. A control module is in electrical communication with the plurality of thermoresponsive modules. The control module is configured to determine a temperature of each thermoresponsive module and to select the at least one heating mode and cooling mode based on the temperature. The heating and cooling mode may be selected in response to a desired dosing profile and/or a biometric condition.
