4.5 Thin MEA: 60ThinMEA
60ThinMEA200/30iR-ITO, 60ThinMEA30/10iR-ITO
60ThinMEAs are only 180 μm "thick", ideally suited for high-resolution imaging. 60ThinMEAs are like
standard MEAs, but the electrodes are embedded in a very thin and delicate glass substrate on a robust
ceramic carrier. The thin glass allows the use of oil immersion objectives with a high numerical aperture.
Like standard MEAs, 59 electrodes and one reference electrode are arranged in an 8 x 8 layout grid with
electrode diameters of 30 μm and interelectrode distances of 200 μm.
60ThinMEAs are also available in a double 5 x 6 layout grid with 10 μm TiN electrodes and 30 μm
interelectrode distance like the High Dense MEA (60ThinMEA30/10iR-ITO).
The flat, round electrodes are made of titanium nitride (TiN).
Tracks and contact pads are made of transparent ITO; insulation material is silicon nitride.
Using 60ThinMEAs
60ThinMEAs are heat-stabilized and can be autoclaved. They can also be coated with different procedures
for cell and tissue cultures.
They should be handled with great care because of the thin and delicate recording area.
