This method has led to a variety of medical applications, particularly in cell studies. In this study, a high voltage of 2 kV/cm with pulse duration of 30 µs was applied on HeLa cell (human cervical cancer cell) to investigate the electroporation process. In addition, this study focused on the effect of protein coated surface, combined with the pulse parameter mentioned above, to look at its effect on HeLa cell when exposed to high voltage.
