There are multiple definitions:

    • implicated in the functions and health of the cardiovascular, nervous, and immune systems as well as in cancer. At low concentrations, NO works as a signal transducer involved in blood flow regulation, smooth muscle relaxation, neurotransmission, and other physiological processes. On the other hand, at high concentrations, it activates cytotoxic defensive mechanisms against pathogens. Fluorescence sensing and imaging have emerged as powerful techniques to monitor the level, localization, and movement of biomolecules in living systems
