  • Method for treatment of an aqueous flux by electropulsation of a field parallel to the flow, pulsation chamber and uses thereof
    Patent number: 6623964
    Abstract: The invention concerns a method for treating an aqueous flow colonized by cells with a pulsed electric field applied to a flow, characterized in that the applied field is substantially parallel to the direction of flow and to its application to the transfer of nucleic acids (RNA, DNA, oligonucleotides) into cells, to the transfer of proteins to cells, to the extraction of cytoplasmic macromolecules and molecules contained in the cells, to cell fusion and the production of hybrids and/or to insertion of membrane proteins. It also concerns an electropulsing chamber, a method for destroying cells and a membrane permeabilization method.
    Type: Grant

    Assignee: Centre National de la Recherche Scientifique
    Inventors: Marie-Christine Vernhes, Pierre-André René Cabanes, Justin Teissie
  • Method for eliminating protozoa, in particular free living amoebas in a colonised aqueous flow, a method for treating an aqueous flow by electropulsing, and its application to eliminating protozoa
    Publication number: 20030165399
    Abstract: The invention relates to a method for treating an aqueous flow colonised by cells by applying a pulsed electric field, in which a colonised aqueous flow is subjected to an electric field of an intensity of 1 to 30 kV/cm, and to its application to destroying protozoa, in particular free living amoebas. It also concerns a method for destroying protozoa.
