novel fluorescent probes for sequential detection of cu2 and Citrate Anion and application in living cell imaging
Dyes and Pigments, 2019Co-Authors: Yongxin Chang, Kun Yao, Xiaobin PangAbstract:Abstract Three novel fluorescent probes (L1, L2 and L3) derived from 2-hydroxyphenyl-4-chloromethyloxazole 8-ydroxyquinaldine were designed and synthesized. The probes showed highly selectively and sensitivity towards Cu2+ ion through “turn off” response in DMF/H2O solution (v/v = 1/1, 0.01 M, Tris-HCl buffer, pH 7.30). The detection limits of probes were up to 8.24 × 10−8 M for Cu2+ ion, which were much lower than drinking water permission concentrations by the United States Environmental Protection Agency. Sequentially, the L1-Cu2+, L2-Cu2+ and L3-Cu2+ complexes detected Citrate Anion (CA) through “turn on” response. The probes, were also found to be reversible and recyclable toward Cu2+ ion and CA controlled “On–Off–On” fluorescent switch and acted as molecular logic gates. Furthermore, the in vivo sensitivity experiments of Cu2+ ion and CA were demonstrated through fluorescence imaging in living cells.

porous ni ca al o bi functional catalyst derived from layered double hydroxide intercalated with Citrate Anion for sorption enhanced steam reforming of glycerol
Applied Catalysis B-environmental, 2021Co-Authors: Chengxiong Dang, Wenwen Yang, Jingxun Zhou, Weiquan CaiAbstract:Abstract The sorption-enhanced steam reforming (SESR) technology may offer a mid-term if not near-term solution to mitigate climate change. A key requirement for the economic operation of SESR processes is the availability of highly effective bi-functional catalysts. Herein, we propose a Citrate intercalated layered double hydroxide (LDH) strategy with in situ formation of carbon template to prepare the Ni-CaO-Ca12Al14O33 bi-functional catalyst featuring highly porous morphologies. The porous structure has inhibited the sintering of Ni and Ca species thanks to the physical isolation effect provided by Citrate Anion intercalation. The as-prepared Citrate-10Ni-CA2.8 displays a very stable performance for 35 reaction-decarbonation cycles in SESR of glycerol, during which H2 purity is retained over 98 % and only 30 % loss in sorption enhancement effect is observed, largely outperforming 10Ni-CA2.8 without Citrate intercalation by 70 %. Moreover, the Citrate Anion intercalation strategy may also guide in designing materials derived from LDH for other high-temperature reactions.

a novel off on fluorescent probe based on carbon nitride nanoribbons for the detection of Citrate Anion and live cell imaging
Sensors, 2018Co-Authors: Donlgliang Yang, Chen Yang, Ning Feng, Zhouwei Shao, Lei Zhang, Xiaodong Wang, Lixing Weng, Zhimin Luo, Lianhui WangAbstract:A novel fluorescent "off-on" probe based on carbon nitride (C₃N₄) nanoribbons was developed for Citrate Anion (C₆H₅O₇3-) detection. The fluorescence of C₃N₄ nanoribbons can be quenched by Cu2+ and then recovered by the addition of C₆H₅O₇3-, because the chelation between C₆H₅O₇3- and Cu2+ blocks the electron transfer between Cu2+ and C₃N₄ nanoribbons. The turn-on fluorescent sensor using this fluorescent "off-on" probe can detect C₆H₅O₇3- rapidly and selectively, showing a wide detection linear range (1~400 μM) and a low detection limit (0.78 μM) in aqueous solutions. Importantly, this C₃N₄ nanoribbon-based "off-on" probe exhibits good biocompatibility and can be used as fluorescent visualizer for exogenous C₆H₅O₇3- in HeLa cells.
