3D MICROELECTRODE ARRAY (MEA) FOR OPTICAL AND ELECTRICAL PROBING OF ELECTROGENIC CELLS

摘要

Disclosed herein are novel 3D microelectrode arrays (3D MEA) that include a substrate body (e.g. chip), microneedles, traces, and a well, wherein the 3D MEA provides for transfer of electrical signals on one side of the substrate body to the other side of the substrate body. Methods for using 3D MEAs to grow electrogenic cells and obtain electrophysiological signals are disclosed as well. Fabrication techniques for producing the 3D MEAs are also disclosed.
