Catecholamine neurotransmitters are crucial molecules for physiological processes in human
metabolism and are involved in the progression of various neurological diseases. Conventional analytical
methods for their determination are based on time-consuming and laboratory intensive procedures.
Hence, a rapid and simple method for the detection of these key brain chemicals is important to improve
the human health and individual quality of life. This can also be helpful to diagnose neurological disorders
at an early stage and to prevent them. In this paper, a brief overview is presented on the latest developments
and applications of electrochemical sensors based on nanostructured tin dioxide (SnO2) for
monitoring some of the most important catecholamine neurotransmitter substances, i.e. dopamine, epinephrine,
and norepinephrine. The potential of these novel electrochemical devices and their outstanding
performances in the field are highlighted.
