A new highly sensitive fluorescence “turn-on” probe (HgP1) based on anthraquinone derivatives for the detection of Hg2+ has been designed and developed. Based on desulfurization effect, probe HgP1 shows high selectivity towards Hg2+ in CH3OH/HEPES (10 mM, pH = 7.4, 1/1, v/v) solution over other analytes. The detection limit for Hg2+ is 8.2 nM. In addition, the probe shows good biocompatibility and
设计和开发了一种基于蒽醌衍生物的新型高灵敏度荧光“开启”探针 ( HgP1 ),用于检测 Hg 2+。基于脱硫效果,探针HgP1在 CH 3 OH/HEPES (10 mM, pH = 7.4, 1/1, v/v) 溶液中对 Hg 2+显示出比其他分析物高的选择性。Hg 2+的检测限为8.2 nM。此外,该探针显示出良好的生物相容性,并已成功用于活细胞成像。
