Impedance based apparatuses and methods for analyzing cells and particles

The invention claims an electrode detecting cell surface and/or device. The device by measuring by the variation of the impedance cells and/or the molecule is detecting cell and/or molecule. A device is a solution of comprises one of the major axis of the substrate terminals'. The electrode arrays (100) is located on the substrate. The electrode array comprises at least two electrodes (110,120), and electrode array; the electrode are at least one side of the insulating material is. The electrode in the widest part is insulation material is a width is 1.5 to 10 times. The device further comprises a conductive pathline 125 (. 130), And extended along the axis the substrate to one of the two end; and (125,130) is not are staggered with the conductive pathlines. The pathline and at least one electrode array is electric.
