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.Type: GrantFiled: July 30, 2019Date of Patent: May 9, 2023Assignees: The Texas A&M University System, The Board of Regents, The University of Texas SystemInventors: Venu G.

Patent number: 10569067Abstract: 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.Type: GrantFiled: November 10, 2016Date of Patent: February 25, 2020Assignees: RAYTHEON COMPANY, THE BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEMInventors: Letia M.
