Mouse thymocytes and erythrocytes are loaded electrically with drugs in isotonic solution. The loaded cells are used for targeting the drugs to specific sites in the organism in order to achieve a controlled drug release in time and space. The field technique used for the loading of the cells is based on the dielectric breakdown of the cell membrane which is observed when cell suspensions are subjected to external field pulses of 2-20 kV/cm for short time intervals (ns to microseconds). When an apparent membrane potential of about 1 V is reached in response to the external field, the membrane breaks down reversibly. The breakdown of the membrane is associated with a remarkable and reversible permeability increase of the cell membrane. The increase in permeability depends on the strength and the duration of the field pulse.
