Cover Feature: Carbon‐Nanotube‐Based Materials for Electrochemical Sensing of the Neurotransmitter Dopamine (ChemElectroChem 2/2019)

Abstract

The Cover Feature shows the detection of neurotransmitter dopamine in the presence of interfering chemical species, such as ascorbic acid and serotonin, using carbon nanotube (CNT)-based materials. The highly conducting nature of functionalized CNTs, with large tensile strength, makes them an ideal non-metallic material for the development of biosensors. Other modifications such as depositing metal or metal-oxide nanoparticles on the CNT surface and coating polymers onto them can significantly increase their properties towards the detection of dopamine. Cyclic voltammetry can detect dopamine through its redox behavior over a wide potential range by using modified CNT electrodes. More information can be found in the Review by N. Gupta and co-workers on page 274 in Issue 2, 2019 (DOI: 10.1002/celc.201801319).
