We designed, fabricated and tested a novel prototype neural interface using two-dimensional single-atom-thick graphene as microelectrode for neural applications. The cytotoxicity indicated a satisfactory biocompatibility and non-toxicity. The treatment graphene with steam plasma improved the biological properties. The action potentials of lateral giant (LG) nerve fiber of the escape circuit of an...
This paper reports an improved method for neglecting the distance effect in extracellular neuron recording and objective comparison of biological and electro-chemical properties between gold (Au) and multi-walled carbon nanotubes (MWCNTs) based microelectrode arrays (MEA). The response amplitude of action potential using MWCNTs that marked by a signal-to-noise ratio (SNR) as high as 50.06± 1.47 dB...
This paper reports an improved method for reducing the impedance of microelectrode array (MEA). The impedance reduction is generally required by increasing the effective surface area of electrode. We have fabricated and treated the multi-walled carbon nanotubes (MWCNTs) based MEA for neuroscience application. The effect of plasma treatment on the surface wettability of MWCNTs was examined and characterized...
