Bioimpedance Measurements and the Electroporation Phenomenon
نویسنده
چکیده
Bioimpedance measurements are used to determine physiological aspects of biological tissues. On the other hand, the electroporation phenomenon causes a variation in the electrical properties of tissue, so it is possible use bioimpedance measurement with the aim of monitor the electroporation phenomenon in real time. The objective of this article is present the basic concepts required to understand bioimpedance measurements and the utility of these for detecting the electroporation effects.

Abstrac t Electroporation or electropermeabilization is a phenomenon observed when lipid bilayers, generally cell membranes, are exposed to high electric field pulses becoming transiently permeable to molecules that under regular conditions are not able to penetrate through them. This change in molecular permeability is believed to be produced by transient aqueous pores created in the lipidic s...

Advancements in microfabrication technology have lead to the development of planar micro-pore electroporation technology. This technology has been shown to provide greater control in single cell manipulation, and electroporation which is independent from cell size. In this work we report direct and spatially resolved characterization of electric currents within a planar micropore electroporatio...
