Jin, X; Hao, L; Hu, Y; She, M; Shi, Y; Obst, M; Li, J; Shi, Z: Two novel fluorescein-based fluorescent probes for hypochlorite and its real applications in tap water and biological imaging, Sensors and Actuators B Chemical, 186, 56-60 (2013), online: 30.05.2013, doi:10.1016/j.snb.2013.05.079 [Link]

Two novel fluorescein-based OCl- chemosensors were designed, synthesized and characterized. Both fluorescence probes utilize an irreversible OCl--promoted oxidation reaction to trigger the activation of fluorescence. These probes were shown to be highly selective for OCl-, and showed real time responses as well as a positive linear relationship to OCl- concentrations. The probes were successfully applied for the detection of OCl- in tap water and for fluorescence imaging of OCl- in bacterial Rhodobacter ferrooxidans sp. strain SW2 cell–EPS–mineral aggregates.
