چکیده
The ability to sense and stimulate cellular tissue electrophysiology is fundamental input/output bioelectronics. Their functionality primarily governed by the structural functional properties of constituent electrode materials. Conventional materials are hindered their two-dimensional topology, high electrochemical impedances, low charge injection capacities, limited stability over chronic timescales. Here, we propose a strategy for obtaining high-surface-area hybrid-nanomaterial efficient I/O bioelectronics conformally templating conductive polymer poly(3,4-ethylenedioxythiophene)–polystyrene sulfonate (PEDOT:PSS) onto nanowire-templated three-dimensional (3D) fuzzy graphene (NT-3DFG). result high-performance material that can leverage exceptional surface area NT-3DFG volumetric storage PEDOT:PSS. Owing its area, microelectrodes exhibit lower impedance up 35-fold greater capacity (CIC) compared conventional metal microelectrodes. Conformally PEDOT:PSS further reduces enhances CIC 125-fold Moreover, NT-3DFG-based nanomaterials stability. Our results highlight importance extrapolating topography 3D developing hybrid miniaturized

The transfer-free fabrication of the high quality graphene on the metallic nanostructures, which is highly desirable for device applications, remains a challenge. Here, we develop the transfer-free method by direct chemical vapor deposition of the graphene layers on copper (Cu) nanoparticles (NPs) to realize the hybrid nanostructures.

متن کاملOn/Off-switchable zipper-like bioelectronics on a graphene interface.
An on/off-switchable graphene-based zipper-like interface is architectured for efficient bioelectrocatalysis. The graphene interface transduces a temperature input signal into structural changes of the membrane, resulting in the amplification of electrochemical signals and their transformation into the gated transport of molecules through the membrane.
