Resumen:
Background: The clinical and therapeutic significance of dopamine, known
as important hormone and neurotransmitter, motivated the development of
the sensitive, rapid, and cost effective electrochemical methods for its
determination.
Methods: This review comments on the advances in the electrochemical
sensing and biosensing of dopamine, covering the period 2005-2015.
Results: The electrocatalytic properties and analytical performances of
the dopamine sensors based on: bare electrodes, electrochemically
pretreated electrodes, chemically modified electrodes (CNTs-, graphene-,
NPs-, MIPs, polymers-, and miscellaneous inorganic and organic
materials-modified electrodes), as well as of the biosensors based on
tyrosinase carbon nanomaterials-modified electrodes and tyrosinase
polymers-modified electrodes are compared and discussed. The presented
data demonstrate that the electrochemical sensors and biosensors based
on CNTs-and graphene-modified electrodes exhibit better analytical
performances compared with the other groups for the sensitive and
respectively for the simultaneous or selective determination of dopamine
in the presence of the interfering species ascorbic acid and uric acid.
Conclusion: The overview of the literature reveals that sensitivity
enhancement and in vivo measurements still remain the challenges in the
development of the electrochemical sensors and biosensors for dopamine
determination.
