Device and method for treating cells

The present invention relates to a device for treating biological cells in an object, the device comprising: - a single winding coil element; - an 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
