Controlled electroporation and mass transfer across cell membranes in tissue

摘要

Electroporation is performed in a controlled manner in individual and multiple biological cells present in biological tissue by monitoring the electrical impedance, defined herein as the ratio of current to voltage in the electroporation cell. The impedance detects the onset of electroporation in the biological cell(s), and this information is used to control the intensity and duration of the voltage to assure that electroporation has occurred without destroying the cell(s). This is applicable to electroporation in general.
