Nano-Neuro interfaces

In addition to the control of neural network topology, we develop ultra-sensitive nano-sensors and their instrumentation to follow spikes propagation along the cells and their networks. Because nanoscale field effect transistors are able to overcome size limitation of conventional capacitive sensors (conventional commercial micro-electrodes), we are integrating silicon nanowires and graphene based FET arrays for multisite recording and stimulation of designable neurons networks. Such highly bio-compatible and highly sensitive bioelectronics appear also suitable for enhancing the time-stability of the current Brain Interfaces.
