Carbon‐Nanotube‐Based Materials for Electrochemical Sensing of the Neurotransmitter Dopamine

Abstract

Abstract The development of new tools with outstanding performance for monitoring neurotransmitters is a challenging task in neuroscience. Electrochemical probes have attracted tremendous attention for the identification and quantification of neurotransmitters, owing to their demonstrated potential for quick response, real‐time measurements, elevated selectivity and sensitivity. In this Review, we have focused on the recent developments of carbon nanotube (CNT)‐based electrochemical sensors for dopamine detection. The use of CNTs is beneficial for this task, because of their high tensile strength, flexibility, good electrical conductivity, and low thermal expansion coefficient. Therefore, electrochemical sensing approaches with CNTs have opened the door for researchers working towards neurobiomedical applications.
