| Abstract Scope |
Reliable brain–machine interfaces (BMIs) demand electrode systems with high biocompatibility, stability, and electrical performance. This work presents a novel nanostructured titanium-based bioelectrode coated with graphene oxide and doped with silver nanoparticles to improve conductivity and reduce impedance at the brain-electrode interface. Surface morphology was analyzed using SEM and AFM, revealing a homogenous nanoporous architecture promoting neural cell adhesion. Electrochemical impedance spectroscopy (EIS) confirmed a 40% reduction in interface impedance compared to commercial Ag/AgCl electrodes.
In-vitro cytocompatibility tests using rat cortical cells demonstrated excellent viability over 7 days, while in-vivo signal acquisition in rodent EEG trials showed enhanced signal-to-noise ratio across the alpha and beta bands. This work advances the development of next-generation bioelectronic interfaces by combining materials engineering and neural signal science. |
