Kan, Chun;Shao, Xiaotao;Wu, Linyun;Zhang, Yao;Bao, Xiaofeng;Zhu, Jing research published 《 A novel “OFF-ON-OFF” fluorescence chemosensor for hypersensitive detection and bioimaging of Al(III) in living organisms and natural water environment》, the research content is summarized as follows. High-selectivity detection of trace Al3+ ions in water and biol. systems by a fluorescence imaging method is not yet mature. Herein, we synthesized a novel reversible Al3+-specific fluorescent probe named RBLF by linking Rhodamine B and pyridine-3-sulfonyl chloride through o-phenylenediamine in several reactions. RBLF exhibited an ultra-high sensitive and excellent selective response towards Al3+ by fluorescence and UV-vis spectra in aqueous solutions What is more worth mentioning is that its response is fast, dual changes in color and fluorescence of the probe solution that can occur instantaneously after adding with Al3+. Its detection limit for Al3+ ions in aqueous system solutions is 14.23 nM, which is far below the maximum allowable amount of Al3+ in drinking water. Moreover, the probe provided an effective method for detecting low concentrations of Al3+ in natural water, living cells, zebrafish and plant tissues.
