Reaching selective fluorescence phosphate detection over pyrophosphate with a cerium-based chemosensor in aqueous media [PDF]
, 2023 Phosphate ions are important molecules used in critical activities, such as those in agriculture or medicine. However, because of their chemical makeup, sensing them using a chemosensor is difficult. In the past, chemists attempted to solve this issue by

Highly Selective Dual Channel Chemosensor Based on benzo[d]thiazole for Detection of Zn2+ ions
International Journal of Electrochemical Science, 2016 A cost effective reversible dual channel chemosensor (BT-1) has been synthesized for detection of Zn2+ ion based on a benzo[d]thiazole Schiff base. It exhibits high selective and sensitive optical changes in fluorescence intensity for zinc metal ions ...

Visible Fluorescence Chemosensor for Saxitoxin [PDF]
The Journal of Organic Chemistry, 2007 Absorption spectra of a number of shellfish extracts have been obtained and reveal prominent absorptions in all samples at 210 and 260 nm and at 325 nm in some of them. These absorptions preclude the use of chromophores with similar absorptions in testing of shellfish samples for paralytic shellfish toxins.
