  • METHOD FOR ACTIVATING THE SURFACE OF POLYMER MATERIALS
    Publication number: 20200239645
    Abstract: The present invention describes a method for chemically and/or biologically activating the surface of originally inert polymeric materials. Activation of the polymer surface occurs by the physical incorporation of at least one linear long chain compound by the inert polymer in the presence of a solvent.
    Type: Application

  • Process for producing polymeric structures that have activated surfaces and activated polymeric structures
    Patent number: 9580838
    Abstract: The present invention relates to a process for producing polymeric structures that have activated surfaces. The process proved to be simple, quick, with high production capacity and low operating costs. The process occurs by depositing a polymer solution, which is assisted by a high electric field, on a conductive liquid surface to produce particles and/or filaments that have an activated surface. More particularly, the process of the present invention has the ability to produce particles and/or filaments that have chemically activated surfaces, in a single process.

  • Method for the immunological diagnosis of Chagas' Disease using recombinant antigens
    Patent number: 5736348
    Abstract: This patent deals with the use of Trypanosoma cruzi antigens obtained using recombinant DNA techniques, or synthetic peptides derived from these antigens, and their use in the immunological diagnosis of Chagas Disease using either ELISA, or western blot, or dot-blot, or hemagglutination, or agglutination, or monoclonal antibodies, or radioimmunoassay. The antigens or synthetic peptides are characterized by displaying the following aminoacid sequences: Ag1: valine (or alanine), alanine, glutamic acid, alanine (orthreonine), glutamic acid, lysine, glutamine, lysine (or arginine), alanine, alanine, glutamic acid, alanine (or serine), threonine (or methionine or alanine) and lysine.
