  • Publication number: 20220234006
    Abstract: A biocompatible membrane composite including a first layer (cell impermeable layer), a second layer (a mitigation layer), and a third layer (a vascularization layer) is provided. The mitigation layer may be positioned between the cell impermeable layer and the vascularization layer In some embodiments, the cell impermeable layer and the mitigation layer are intimately bonded to form a composite layer having a tight/open structure. A reinforcing component may optionally be positioned on either side of the biocompatible membrane composite or within the biocompatible membrane composite to provide support to and prevent distortion of the membrane composite. The biocompatible membrane composite may be used in or to form a device for encapsulating biological entities, including, but not limited to, pancreatic lineage type cells such as pancreatic progenitors.

  • Publication number: 20220233299
    Abstract: Cell encapsulation devices for biological entities and/or cell populations that contain at least one biocompatible membrane composite are provided. The cell encapsulation devices mitigate or tailor the foreign body response from a host such that sufficient blood vessels are able to form at a cell impermeable surface. Additionally, the encapsulation devices have an oxygen diffusion distance that is sufficient for the survival of the encapsulated cells so that the cells are able to secrete a therapeutically useful substance. The biocompatible membrane composite is formed of a cell impermeable layer and a mitigation layer. The cell encapsulation device maintains an optimal oxygen diffusion distance through the design of the cell encapsulation device or through the use of lumen control mechanisms. Lumen control mechanisms include a reinforcing component that is also a nutrient impermeable layer, internal structural pillars, internal tensioning member(s), and/or an internal cell displacing core.

  • Publication number: 20220233298
    Abstract: A biocompatible membrane composite that can provide an environment that is able to mitigate or tailor the foreign body response is provided. The membrane composite contains a mitigation layer and a vascularization layer. A reinforcing component may optionally be included to provide support to and prevent distortion of the biocompatible membrane composite in vivo. The mitigation layer may be bonded (e.g., point bonded or welded) or adhered (intimately or discretely) to an implantable device and/or cell system. The biocompatible membrane composite may be used as a surface layer for implantable devices or cell systems that require vascularization for function but need protection from the host's immune response, such as the formation of foreign body giant cells. The biocompatible membrane composite may partially or fully cover the exterior of an implantable device or cell system. The mitigation layer is positioned between the implantable device or bioactive scaffold and the vascularization layer.

  • Patent number: 11332531
    Abstract: This application provides isolated antibodies, and antigen-binding fragments thereof, that specifically bind Programmed Death Ligand-1 (PD-L1). These PD-L1 antibodies, or antigen-binding fragments thereof, have a high affinity for PD-L1, function to inhibit PD-L1, are less immunogenic compared to their unmodified parent antibodies in a given species (e.g., a human), are capable of increasing T-cell proliferation and IL-2 secretion in a mixed lymphocyte reaction, and can be used to treat human diseases (e.g., cancer, infectious diseases, autoimmune diseases, asthma, transplant rejection, and inflammatory disorders).

  • Patent number: 11243159
    Abstract: A tunable colorimetric sensor/optical filter is based on a lithography-free, asymmetric Fabry-Perot cavity. The sensor has a thin-film structure formed by a lossy, porous nanoplasmonic top film deposited on an actively tunable spacer middle layer, and a reflective base layer (either a metal or semiconductor). The structure is fabricated using wafer-scale PVD processes, and the middle layer responds to the presence of a stimulus in the local environment, by expanding in thickness resulting in a shift in resonance wavelength and thus an obvious change in color of the sensor, which color change is detectable by the naked-eye. Such layered geometries exhibit vibrant, macroscopic structural coloration owing to the broadband optical absorption of the top film, enabling the change in spacer thickness to be transduced visually, circumventing the need for sophisticated optical equipment for signal readout to observe the presence of the environmental stimulus.

    Abstract: A semiconductor device for a volatile memory is disclosed. The semiconductor device includes a substrate, a side wall and an epitaxial liner. The substrate has a first height and is made of a first material having a first lattice parameter. The side wall defines a deep trench. The epitaxial liner is disposed around the side wall, is made of a second material having a second lattice parameter, and has a second height having a same level with the first height, wherein the epitaxial liner and the side wall cooperate for creating a desired aspect ratio for the deep trench.

  • Patent number: 11141868
    Abstract: A joint attachment system for a reconfigurable truss includes a first joint attachment having a first pivot axis and a second joint attachment having a second pivot axis. The first joint attachment and second joint attachment form a concentric spherical joint linkage when attached to a first body member and a second body member, respectively. The first pivot axis of the first joint attachment intersects the second pivot axis of the second joint attachment at a single point X which defines a center of the concentric spherical joint linkage. The concentric spherical joint linkage is configured to allow the addition of one or more joint attachments and body members to the truss node. In addition, the concentric spherical joint linkage is configured to allow the removal of one or more joint attachments and body members from the truss node.
