Microelectrode supporting cell with excitable membrane
First Claim
1. A microelectrode intended to support at least one cell with an excitable membrane immerged in a fluid, including an insulating plate (11, 51) provided with openings, each opening emerging on a detection electrode (13, 54) and being surrounded with walls made of insulating material, substantially perpendicular to the plate to block in position said at least one cell, characterized in that it further includes spacing means (26-29) for maintaining said at least one cell at a determined distance from the corresponding electrode, said distance being occupied by said fluid.

Abstract
The invention concerns a microelectrode designed to support at least a cell with excitable membrane, comprising an insulating wafer (11) whereon are formed detecting electrodes. A cover above each electrode is enclosed with walls made of insulating material substantially perpendicular to the wafer for locking in position said at least one cell. Spacing means (26-29) enable said at least one cell to be at a specific distance from the corresponding electrode.
