3D MEAs for recording from inner cell layers

Date: 
2019-11-05

Planar electrodes reach their limits when it comes to tissue slices or cell clusters. The outer cell layers often contain dead cells which shield the cell signals of inner cell layers from the electrodes. The 3D electrodes of the 3D-MEAs penetrate 40 to 100 µm deep into the tissue and make recording from inner cell layers possible.

3D-MEAs are available in 4 versions:

Overview 3D MEA types
Product name Interelectrode distance Electrode diameter Electrode height
60-3DMEA100/12/40iR-Ti 100 µm 12 µm 40 µm
60-3DMEA200/12/50iR-Ti 200 µm 12 µm 50 µm
60-3DMEA200/12/80iR-Ti 200 µm 12 µm 80 µm
60-3DMEA250/12/100iR-Ti 250 µm 12 µm 100 µm

 

All types have 60 electrodes, are based on glass, and feature TiN electrodes (same as standard MEAs).
