  • Development and characterization of f-gelatin electrospun scaffolds for cardiac tissue modeling
    Patent number: 12187888
    Abstract: Cardiac tissue-on-a-chip platforms aimed at mimicking human cardiac tissue structures, are valuable tools to model, and serve as preclinical platforms for drug testing or therapies for cardiac repair. We have developed three types of electrospun scaffolds including furfuryl gelatin (f-gelatin) alone, with polycaprolactone (PCL) in the ratio of f-gelatin and PCL (1:1), and coaxial scaffolds with PCL (core) and f-gelatin (sheath). Scaffolds were developed through single nozzle electrospinning and coaxial electrospinning, respectively, to serve as scaffolds for cardiac tissue-on-a-chip platforms.
    Type: Grant
    Filed: April 18, 2023
    Date of Patent: January 7, 2025
    Assignee: Board of Regents, The University of Texas System

  • Methods and polymer compositions for material extrusion 3D printing
    Patent number: 10954369
    Abstract: Methods and compositions directed to blends of acrylonitrile butadiene styrene (ABS) with styrene ethylene butadiene styrene (SEBS) are disclosed. In certain aspects, the blends further include an ultrahigh molecular weight polyethylene (UHMWPE). In a further aspect, the blends are compatible with 3D printing platforms.
