A novel composite gold/gold nanoparticles/carbon nanotube electrode for frequency-stable micro-electrical impedance tomography
2020
A novel electrode structure is introduced for micro-electrical impedance tomography. The composite electrode structure is made up of gold nanoparticles (AuNPs) and carbon nanotube (CNT) which are deposited on the surface. The nanostructure-based composition of electrodes improved the effective surface area, increased the double-layer capacitance of electrodes, and enhanced the electron transfer on the electrode–analyte interface. The proposed electrodes exhibit lower frequency-dependent electrical properties in impedance measurement.
