Abstract:
1. A method of focusing an electric field within a defined electric field to facilitate electroporation within a biological entity, the method comprising the steps of: establishing an electric field between at least one first active electrode and at least one second active electrode within the biological entity, the established electric field having an electric field intensity concentration focus; and changing the focus of the electric field intensity concentration to facilitate electroporation at a desired focus location within the biological entity by positioning a passive electrode within the electric field established between the at least one first active electrode and the at least one second active electrode, wherein the passive electrode is fabricated of a material selected from the group consisting of metals, semiconductors, nanoparticles, plastics, polymers, bio-polymers, fluidistic substances, bio-molecules, non-conductive materials and high relative permittivity materials, wherein the passive electrode is not a current source or a current sink for the established electric field, wherein the passive electrode is never physically or electrically coupled to a source of electrical energy and wherein the passive electrode is never physically or electrically coupled to another passive electrode or to a conducting element.
