ABSTRACT:
Systems and methods of measuring resistances of samples to be electroporated and utilizing the measured resistances in the electroporation are provided. During an electrical pulse sent to the sample, a time and a corresponding voltage drop on a known capacitance is measured to determine the sample resistance. A constant voltage may be assumed, and the voltage drop across a known resistance in series with the sample resistance is used to determine the sample resistance. Based on the value of the sample resistance, an electrical pulse may be altered by changing a value of a parallel resistance.
