Abstract
A method and a device are used for carrying out measurements on cells located in a liquid environment. Each cell is positioned with an underside of its membrane on a surface having a channel running through it. A negative pressure is established to aspirate the cells. Each cell is electrically scanned via at least one electrode which is spaced apart from the cell. The negative pressure is preferably established in a pulse-like manner to rupture the membrane in such a way that the cell interior enclosed by the membrane is connected to the channel.
