A new fast response colorimetric and fluorescent probe for the detection of bisulfite and its application on test strips JiangChen YaoYuewei MengJingjing YaoCheng 2019 <p>A new carbazole-based colorimetric and fluorescent probe <b>CBB</b> for the detection of bisulfite (HSO<sub>3</sub><sup>−</sup>) has been developed via nucleophilic addition reaction. Probe <b>CBB</b> can detect HSO<sub>3</sub><sup>−</sup> with excellent sensing properties including high selectivity and sensitivity, fast response (5 s). More importantly, probe <b>CBB</b> system not only can be applied to monitor HSO<sub>3</sub><sup>−</sup> in environment with excellent solid properties based on test strips but also can be used for the detection of HSO<sub>3</sub><sup>−</sup> in real-water samples with satisfactory results.</p>
