Adhesion to carbon nanotube conductive scaffolds forces action-potential appearance in immature rat spinal neurons.

In the last decade, carbon nanotube growth substrates have been used to investigate neurons and neuronal networks formation in vitro when guided by artificial nano-scaled cues. Besides, nanotube-based interfaces are being developed, such as prosthesis for monitoring brain activity. We recently descr...
