The present invention relates to a device for treating biological cells in an object, the device comprising: &mdasha single winding coil element &mdashan electrical generator connected to the single winding coil element, the single winding being configured to be positioned essentially around the object wherein the electrical generator is configured to discharge into the single winding coil element so that the single winding coil element generates a short duration pulsed electromagnetic field by magnetic induction in the single winding coil element, the electromagnetic field having a field strength that is sufficiently high to affect, preferably increase the permeability of cell membranes and/or intracellular membranes of the biological cells contained in the object when in operation the object is placed inside the single winding coil element.
