Abstract:
Electroporation is a widely-used methodology for permeabilization of cells using pulsed electric field (PEF). In this paper, we compare the electroporation efficiency in terms of molecular transport and the generated reactive oxygen species (ROS) between low (1 Hz) and high (1 MHz) frequency nanosecond range PEF bursts. We used aluminum, copper and stainless-steel electrodes and evaluated the influence of electrode material on ROS generation and electroporation. Bursts of 25 or 50 pulses of 7-14 kV/cm amplitude and 200 ns duration were applied, and the results were compared to those obtained using electroporation with pulses of equivalent energy in conventional microsecond range. It was determined that electroporation efficiency scales with ROS generation and is highly affected by the material of electrodes and by the applied pulsing protocols. We present experimental evidence that metal ions, and not the pH fronts near the electrodes, play a major role in generation of ROS during electroporation.

Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...
