Abstract:

Transparent microelectrode arrays have emerged as increasingly important tools for neuroscience by allowing simultaneous coupling of big and time-resolved electrophysiology data with optically measured, spatially and type resolved single neuron activity.Scaling down transparent electrodes to the length scale of single neuron is challenging since conventional transparent conductors are limited by their capacitive electrode/electrolyte interface.  Here, we establish transparent microelectrode arrays with high performance, great biocompatibility and comprehensive in vivo validations from a recently developed, bilayer-nanomesh material composite, where a metal layer and a low-impedance faradaic interfacial layer are stacked reliably together in a same, transparent nanomesh pattern.
