Competitive binding like that in immunoassays is the principle behind the chemosensor based on receptor 1 , which was used to measure the concentration of citrate ( 2 ) in a series of common beverages. Citrate displaces the fluorescent colorimetric probe 5‐carboxylfluorescein ( 3 ) from 1 , and the process can be monitored by UV or fluorescence spectroscopy.
