Review—Progress on Carbon-Based Electrochemical Sensors for Epinephrine and Norepinephrine

Epinephrine and norepinephrine are neurotransmitters which also serve as hormones, and they influence different functions of our body and stimulate the central nervous system. Because any disorder in their concentration level may cause serious health issues, monitoring their concentration at every stage of production in the body as well as therapeutic treatment are vital. Carbon materials play a key role in improving the electron transfer rate in electrochemical sensing due to their active surface area and superior electron transfer efficiency. The present review focuses on carbon-based electrochemical sensors for epinephrine and nor epinephrine.
