Disclosed is a method for treating biological material via electrical current, in which the biological material is added to a small volume of a buffer solution having relative high ionic strength. A strong electrical field is generated in the buffer solution by a high voltage pulse having a preset duration. The biological material is added to at most 50 mul of a buffer solution with an ionic strength of at least 100 mmol/l. By at least one voltage pulse having a preset duration of at least 10 mus, an electrical field with a field strength of at least 1 kV/cm is generated in the buffer solution. The voltage pulse is hereby interrupted at least once for a duration of at least 100 mus and is then again continued.
