Mechanistic studies of skin electroporation using biophysical methods

The mechanism by which high-voltage pulses transiently disrupt lipid bilayers in cell membranes has been the subject of controversy since electroporation was first observed almost three decades ago. Determining the mechanism by which such pulses permeabilize the complex, multilamellar bilayer structures in skin poses an even greater challenge. To address this issue, a range of methods have been employed to perform biophysical characterization for skin electroporation studies. In this chapter, we provide an overview of these methods and highlight representative findings which biophysical characterization has yielded.
