Seven days old seedlings of Arabidopsis thaliana, suspended in a 0.4 S/m buffer solution were exposed to nanosecond pulsed electric fields (nsPEF) with a duration of 10 ns, 25 ns and 100 ns. The electric field was varied from 5 kV/cm up to 50 kV/cm. The specific treatment energy ranged between 100 J/kg and 10 kJ/kg. Due to electroporation of the plasma membrane of the plant cells, the seedlings completely...
Summary form only given. Wastewater from hospitals carries large number of pathogenic and increasingly antibiotic resistant bacteria, which could spread in the environment. The pulsed electric field (PEF) treatment of wastewater as a non-chemical disinfection method is a suitable alternative method for reducing this bacterial freight. In the literature it was figured out, that continuous flow PEF...
With the application of pulsed electric fields of only nanosecond duration but field strengths of several megavolts per centimeter, apoptosis can be induced in tumor cells. The detailed mechanisms of this process are not yet completely understood. The accumulation of charges along the membranes in the applied electric field is likely the primary trigger. This first response is observed as a sudden...
In order to study membrane charging in mammalian cells during exposure to pulsed electric fields of 60 ns duration we measured transmembrane voltage changes during and after exposure in real-time, i.e. with a resolution that is short compared to the duration of the administered electrical pulse. The applied electric field was varied between 5 kV/cm and 90 kV/cm. Under all conditions the voltage at...
