Nanocomposite Materials based on Metal Nanoparticles for the Electrochemical Sensing of Neurotransmitters

Neurotransmitters (NTs) are known as endogenous chemical messengers with important roles in the normal functioning of central and peripheral nervous systems. Abnormal levels certain NTs, such dopamine, serotonin epinephrine, have been linked several neurodegenerative diseases (such Alzheimer’s disease, Parkinson’s disease Huntington’s disease). To date, various strategies employed for quantitative determination nanocomposite materials based on conducting polymers metal nanoparticles constitute a cornerstone development electrochemical sensors low costs, stability, fast response rates high selectivity sensitivity. The preparation analytical applications sensing neurotransmitters discussed this paper. Recent developments also emphasis benefits brought by improving sensitivity measurements. synthesis methods situ generation within polymer layers reviewed. nanocomposite-sensing towards detection epinephrine terms quantification limits, linear range, selectivity.
