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

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. CNTs on the fishing job: The detection of the neurotransmitter dopamine by using conductive and tensile non‐metallic carbon nanotubes (CNTs) is described. Three main types of materials have been developed in this regard, including metal or metal oxide nanoparticles supported on CNTs, polymer‐coated CNTs, and functionalized CNTs grown on glassy carbon electrodes.
