A highly selective and sensitive electrochemical sensor for dopamine based on a functionalized multi-walled carbon nanotube and poly(N-methylaniline) composite

Abstract

Dopamine (DA) is an important neurotransmitter used for diagnosing various diseases from its abnormal concentrations in human fluids. Herein, an electrochemical sensor based on a composite of re-doped poly(N-methylaniline) (rePNMA)...

Multiwavelength Raman spectroelectrochemical study of poly(N-methylaniline): An overview

“…Lithium-sulfur batteries are known to suffer from the dissolution of polysulfides during the charging process, thus, coating the cathode surface by the layer of PNMA was reported to reduce the loss of active material and to improve the cycle stability [1]. A composite of redoped PNMA and multiwalled carbon nanotubes was prepared and used as an active material for creating of a highly selective and sensitive electrochemical sensor for dopamine, that can be used even in the presence of some interfering species [2]. Nanoporous graphitic nitrogen-doped carbon hollow spheres were prepared via the direct pyrolysis of nanostructured PNMA, and enhanced electrochemistry-related properties of the resulting material were reported, including a high specific capacitance with no loss even after 5,000 cycles of charging-discharging, and an efficient electrochemical oxygen reduction reaction [3].…”
