This paper reports a near-infrared chemosensor for phosphate ions (Pi) based on Pi-controlled fluorescence off-on switching mechanism. The Pi sensor displayed colorimetric responses towards Pi with a distinct color change from green to yellow in aqueous media. Apyrase, a hydrolytic enzyme, was used to accelerate the endogenous Pi production for evaluating in vivo fluorescent sensing ability of the...
Two coumarin-based fluorescence probes, 1 and 2, containing a methoxy oxalyl group as a reaction site were developed. These two novel probes displayed an instant turn-on fluorescence response specific towards Pi without interference from ATP and PPi. A selective 23-fold increase in fluorescence for 1 (in DMSO–HEPES) and a 20-fold increase for 2 (in DMSO) were observed. The proposed sensing mechanism...
