Electrical stimulation using implantable electrodes is widely used to treat various neuronal disorders such as Parkinson’s disease and epilepsy and is a widely used research tool in neuroscience studies. However, to date, devices that help better understand the mechanisms of electrical stimulation in neural tissues have been limited to opaque neural electrodes. Imaging spatiotemporal neural. These properties can be achieved by coatings with platinum nanoparticles [19,20], carbon nanotube [21, 22], polymer nanotubes [23] or multilayer approach of carbon nanotubes and conductive polymer.

Carbon nanotube, also called buckytube, nanoscale hollow tubes composed of carbon cylindrical carbon molecules feature high aspect ratios (length-to-diameter values) typically above 10 3, with diameters from about 1 nanometer up to tens of nanometers and lengths up to unique one-dimensional structure and concomitant properties endow carbon nanotubes with special.   T. Gabay, M. Ben-David et al., Electro-chemical and biological properties of carbon nanotube based multi-electrode arrays. Nanotechnology 18 (3) () [ PubMed ] Gabriel G, Gomez R, et al. Easily made single-walled carbon nanotube surface microelectrodes for neuronal applications.

We present a novel prototype neural interface using vertically aligned multiwalled carbon nanotube (CNT) pillars as microelectrodes. Functionalized hydrophilic CNT microelectrodes offer a high charge injection limit (1− mC/cm2) without faradic reactions. The first repeated in vitro stimulation of hippocampal neurons with CNT electrodes is demonstrated.   The elastomeric electrodes of the present solid-state supercapacitors are made by using giant inserted twist to coil a nylon sewing thread that is helically wrapped with a carbon nanotube .
