Patents Assigned to Pathogen Removal and Diagnostic Technologies, Inc.
  • Patent number: 9678085
    Abstract: Ligands that bind to prion proteins and methods for using the ligands for detecting or removing a prion protein from a sample, such as a biological fluid or an environmental sample. The ligands are capable of binding to one or more forms of prion protein including cellular prion protein (PrPc), infectious prion protein (PrPsc), and recombinant prion protein (PrPr). Prions from various species, including humans and hamsters, are bound by the ligands. Also provided is a method of treating or retarding the development of a prion-associated pathology in a subject.

  • Patent number: 9091006
    Abstract: The present invention describes a novel process for the conformal coating of polymer fibers of nonwoven substrates. This process is based on modification of polymer fiber surfaces by controlling the degree of etching and oxidation to improve adhesion of initiators to the surface and to facilitate subsequent conformal polymer grafting. The modified fiber surfaces render new functionalities to the surface, such as increased hydrophilicity, attached ligands or changed surface energy. The invention includes the modified polymer fibers produced by the process described herein.
