Electroporation Theory

The application of an intense electric field in cell suspension or biological tissue produces pores in the plasmatic membrane; this process is called electroporation or electropermeabilization. The pores facilitate the introduction of molecules into the cell and tissue. Electroporation has applications in the treatment of tumors, genetics, and immunology.

The electroporation dynamics (opening and closing of pores) is not completely understood, in part because electroporation is evaluated by indirect measurements.

A set of possible methods for estimating electroporation could be based on measurements of the electrical properties of the tissues or cells electroporated. These electrical properties have been proposed to verify the electroporation effectiveness in individual cells, cell suspensions  and tissues.
