by measuring the electro-osmotic flow velocity of buffer through a glass capillary , on the inner surface of which cells have been grown , the zota-protential of these cells can be determined without the changes in zota-potential , viability and morphology caused by the chemical , enzymatic or mechanical pretreatment hitherto necessary for cell dispersion in the microelectrophoretic method .
