  • Patent number: 11898132
    Abstract: A bioreactor and method of forming complex three-dimensional tissue constructs in a single culture chamber. The bioreactor and methods may be used to form multi-phasic tissue constructs having tissue formed from multiple cell types in a single culture chamber. The bioreactor includes at least one translation mechanism to facilitate translation of one or more tissue constructs without direct user intervention, thereby providing a closed, sterile environment for complex tissue fabrication. The bioreactor may be used as a stand-alone device or as part of a large-scale system including many bioreactors. The large-scale system may include a perfusion system to monitor and regulate the tissue culture environment.

  • Publication number: 20220243156
    Abstract: A bioreactor capable of producing complex, three-dimensional tissue constructs has improved media transfer and increased controllability with regard to exposure to the external environment. The bioreactor includes an external surface, a first tissue culture side for culturing a first cell source in a first tissue culture support region, a second tissue culture side for culturing a second cell source in a second tissue culture support region, and a plurality of ports. At least one of the ports of the plurality of ports extend from the first tissue culture support region of the first tissue culture side to the external surface. The plurality of ports can include an external port that is configured to be a liquid inlet when the bioreactor is in a first orientation and a gas outlet when the bioreactor is in a second orientation.

  • Patent number: 10160833
    Abstract: Dissociation of a macroscale version of an aramid fiber leads to the nanofiber form of this polymer. Indefinitely stable dispersions of uniform high-aspect-ratio aramid nanofibers (ANFs) with diameters between 3 and 30 nm controlled by the media composition and up to 10 ?m in length are obtained. ANFs can be processed in transparent thin films using layer-by-layer assembly (LBL) with superior mechanical performance.

  • Patent number: 10101129
    Abstract: A protective device and method of design to protect against multiple blast and impact events for use in any application in which a delicate target has to be protected. The protective device for mitigating the effects of blast or impact employs a first layer having a first acoustic impedance and a second layer having a second acoustic impedance. The second acoustic impedance is different than the first acoustic impedance. The second layer is proximate to the first layer. The first layer and the second layer are chosen collectively to tune the stress waves from the blast or impact events to one or more specific tuned frequencies. A third layer of a visco-elastic material is employed having a critical damping frequency that matches one or more specific tuned frequencies to dissipate the stress waves of the blast and impact event. The third layer is proximate to the second layer.
