| Title: | Reaction-based europium complex for specific detection of cysteine over homocysteine and glutathione with variable-temperature kinetic studies | Authors: | Yip, YW Yan, Z Law, GL Wong, WT |
Issue Date: | 14-Feb-2019 | Source: | European journal of inorganic chemistry, 14 Feb. 2019, v. 2019, no. 6, p. 813-820 | Abstract: | A water-soluble europium(III)-based probe, EuL, has been designed and synthesized for selective recognition of cysteine (Cys) over other structurally similar thiols and amino derivatives due to formation of a more stable and preferable seven-membered ring. Addition of Cys shows a significant response with quenching of over 90 % of the initial signal (Hcys: 10.5 %, GSH: 3.6 % respectively). A good linear correlation between the emission intensities and concentrations of Cys has been established. | Keywords: | Cysteine Europium Macrocycles Reaction mechanisms Sensors |
