}An NH4Cl-superfused system for a cell-cultured pH-sensing transistor was developed for detecting ion leakage across the plasma membranes of model HepG2 cells. The screening of chemical species by the method developed and conventional membrane-leakage assays identified the types of membrane injuries: structural membrane disruption and pore formation. Apoptosis-mediated membrane disordering was detected by continuously monitoring the ion-barrier breakdown of the membranes using the transistor…
