  • Method of forming microparticles for use in cell seeding
    Patent number: 10329528
    Abstract: The present invention is directed to methods for forming microparticles useful for cell seeding and for conjugating protein to the surface of the microparticles. The method comprises co-injecting an organic solution of PLGA or other polymer with an aqueous solution into a flow focusing tube.
    Type: Grant
    Filed: April 6, 2017
    Date of Patent: June 25, 2019
    Assignee: The Curators of the University of Missouri

  • Systems and methods for endotoxin removal from fluids
    Patent number: 9918943
    Abstract: Systems and methods are provided for the removal of endotoxins from fluids. The methods can include the use of polymeric nanoparticles for binding endotoxins present in a fluid. The polymeric nanoparticles can be associated with a support member. The polymeric nanoparticles can have an endotoxin removal capacity of at least 1×109 endotoxin units per gram of polymeric nanoparticle (EU/g) and/or a removal efficacy per unit surface area of the polymeric nanoparticles of at least 1×106 EU/cm2.
