摘要
The present invention relates to a microfluidic device for determining the transepithelial electrical resistance (TEER) of a cell layer or a cell assembly and/or for determining the impedance of cells, a cell layer or a cell assembly, said device comprising at least one microchannel (1) comprising at least a lower (3) and an upper compartment (2) separated by at least one porous membrane (4) and optionally an inner compartment (12), the lower compartment (3) comprising a bottom wall (7) and side walls (8), the upper compartment (2) comprising an upper wall (6) and side walls (8), the bottom (7) and upper wall (6), the side walls (8) and the at least one porous membrane (4) defining compartment volumes, wherein at least one porous membrane (4) comprises on its surface at least one electrode (5).
