Chemical sensing of neurotransmitters.

In the past few decades, the development of chemosensors for neurotransmitters has emerged as a research area of significant importance, which attracted a tremendous amount of attention due to its high sensitivity and rapid response. This current review focuses on various neurotransmitter detection based on fluorescent or colorimetric spectrophotometry published for the last 12 years, covering biogenic amines (dopamine, epinephrine, norepinephrine, serotonin, histamine and acetylcholine), amino acids (glutamate, aspartate, GABA, glycine and tyrosine), and adenosine.
