Electrochemical Detection of Adrenaline on Pyrolytic Electrode Coated with Carbon Nanotubes

摘要

Carbon nanotubes (CNTs) have received considerable attention as sensors because of their nano-size and superior electron transfer kinetics. These properties make them an attractive candidate as electrode material for neurotransmitter detection using Fast Scan Cyclic Voltammetry (FSCV). Electrochemical detection of adrenaline in the brain is challenging because of the overlapping signals from other analytes. In this report, we show that adrenaline electrochemical detection can be improved by coating pyrolytic electrodes with CNTs.
