Electrochemical Detection of Gasotransmitters: Status and Roadmap.

Gasotransmitters, including nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (HS), are a class of gaseous, endogenous signaling molecules that interact with one another in the regulation of critical cardiovascular, immune, and neurological processes. The development of analytical sensing mechanisms for gasotransmitters, especially multianalyte mechanisms, holds vast importance and constitutes a growing area of study. This review provides an overview of electrochemical sensing mechanisms with an emphasis on opportunities in multianalyte sensing.
