Numerical modeling in electroporation-based biomedical applications

Numerical modeling in electroporation-based biomedical applications

Background. Numerous experiments have to be performed before a biomedical application is put to practical use in clinical environment. As a complementary work to in vitro, in vivo and medical experiments, we can use analytical and numerical models to represent, as realistically as possible, real biological phenomena of, in our case, electroporation. In this way we can evaluate different electri...

Numerical modeling for in vivo electroporation.

Electropermeabilization of cell plasma membrane is a threshold phenomenon. When a cell is exposed to electric field a spatially dependent transmembrane potential is induced (1). Above a certain threshold value of transmembrane potential permeability of plasma membrane drastically increases. Thus, in order to obtain plasma membrane permeabilization an above threshold transmembrane potential need...

Electroporation-based applications in biotechnology.

Electroporation is already an established technique in several areas of medicine, but many of its biotechnological applications have only started to emerge; we review here some of the most promising. We outline electroporation as a phenomenon and then proceed to applications, first outlining the best established - the use of reversible electroporation for heritable genetic modification of micro...

Avoiding nerve stimulation in irreversible electroporation: a numerical modeling study.

Electroporation based treatments consist in applying one or multiple high voltage pulses to the tissues to be treated. As an undesired side effect, these pulses cause electrical stimulation of excitable tissues such as nerves and muscles. This increases the complexity of the treatments and may pose a risk to the patient. To minimize electrical stimulation during electroporation based treatments...
