Influence of electric pulse duration on the action on a biological cell

Summary form only given, as follows. Electric pulses are widely used for manipulation of biological cells, for example, cell fusion, rotation, dielectrophoresis, and electroporation. In recent years, the biological effects of ultrashort (/spl sim/ns) electric pulses on cells and tissues were studied and reported. It is obvious that parameters like pulse height, duration, front edge, back edge, and repetition rate, of an electric pulse are all important for biological effects arising from the pulse. There are plenty of experiment studies of the influence of these parameters. We report our analysis and calculation results of the influence of pulse duration. The tendency of our calculation results is consistent with experiment results.
