  • Patent number: 10220364
    Abstract: Disclosed herein is a method of: treating an organic polymer with an electron beam-generated plasma; exposing the treated polymer to air or an oxygen- and hydrogen-containing gas, generating hydroxyl groups on the surface of the polymer; reacting the surface with an organosilane compound having a chloro, fluoro, or alkoxy group and a functional or reactive group that is less reactive with the surface than the chloro, fluoro, or alkoxy group; and covalently immobilizing a biomolecule to the functional or reactive group or a reaction product thereof.
    Type: Grant
    Filed: April 13, 2018
    Date of Patent: March 5, 2019
    Assignee: The United States of America, as represented by the Secretary of the Navy
    Inventors: Stella H. North, Evgeniya H. Lock, Scott G. Walton, Chris Rowe Taitt

  • Publication number: 20180064527
    Abstract: Synthetic human blood vessels can be constructed using human brain derived endothelial cells and incorporated into a tissue model that contains astrocytes and other neurons and microglia. Multi-cell type microvessels incorporate cell types such as astrocytes and pericytes in order to construct a highly representative blood-brain barrier in vitro model with a functional lumen containing brain-derived microvascular endothelial cells and a polymer wall containing human astrocytes and/or pericytes.
