Multi-walled carbon nanotube based multi-electrode arrays for the detection of the emergent activity in the cortical network.

Highlights: [•] A process to modify microfabricated platinum electrodes with carbon nanotubes. [•] The process is based on standard processing and compatible with large scale. [•] The electrodes show improved sensitivity and electric charge transfer. [•] The electrodes enable enhanced neural activity recording from cortical slices. [ABSTRACT FROM AUTHOR]
