Development of a new water-soluble fluorescence probe for hypochlorous acid detection in drinking water.

Responsive small-molecule fluorescence probe specific for target analyte detection is an emerging technology for food safety and quality analysis. In this work, we report a new water soluble small-molecule fluorescence probe () for the detection of hypochlorous acid (HOCl) in drinking water samples. Probe was developed by coupling of a glucosamine into 10-methyl-10H-phenothiazine fluorophore with a HOCl-responsive C=N bond.
