Protein assisted fluorescence enhancement of a dansyl containing fluorescent reagent: detection of Hg+ ion in aqueous medium.
نویسندگان
چکیده
Intramolecular charge transfer (ICT) based fluorescent reagents containing a dansyl fluorophore have been synthesized and characterized. The reagent 1 and its complex, 1+Hg(2+) in sodium acetate buffer (pH 6.7) revealed considerable fluorescence enhancement (switched-on) in the presence of bovine serum albumin (BSA) with 10 ppb detection sensitivity. (1)H NMR spectral analysis suggests complexation between 1 and Hg(2+) ion involving the N,N-dimethylamino and carboxylic functions.

A graphene oxide-terpyridine conjugate (GOTC) based colorimetric and fluorescent nano-chemosensor was synthesized. It showed high selectivity and sensitivity for Fe2+ and Fe3+ ions in neutral aqueous solution over other metal ions such as Li+, Na+, Ba2+, Ca2+, Al3+, Cd2+, Co2+, Cu2+, Hg2+, Mn...
متن کاملA highly sensitive and selective detection of Hg(II) in 100% aqueous solution with fluorescent labeled dimerized Cys residues.
A simple design of a ratiometric fluorescent sensor for detecting Hg(II) ion in 100% aqueous solution was demonstrated, based on the structure of dimerized Cys residues with two dansyl fluorophores. The sensor highly sensitively and selectively detected mercury ion (K(d) = 41 nM) in 100% aqueous solution via a turn-on and ratiometric response. The sensor showed no interferences of other metal i...

A novel reversible fluorescence turn-on chemosensor 1 for Hg(2+) was constructed based on a new receptor composed of an S atom and an alkene moiety. The sensor showed a large fluorescence enhancement response (1000-fold enhancement), high selectivity, and high sensitivity with a detection limit of 27.5 nM. Significantly, the reversible sensor functioned well in the near pure aqueous medium and ...
متن کاملSelective and sensitive fluorescence-shift probes based on two dansyl groups for mercury(ii) ion detection.
Two probes ( and ) bearing two dansyl fluorophores were synthesized and applied to the detection of mercury(ii) ions in aqueous solution. These probes exhibited a selective response to Hg(2+) in a buffered solution, with high sensitivity and a unique fluorescence response signal which displayed a blue-shift effect in the fluorescence emission peak. The Hg(2+) recognition mechanisms of the probe...
متن کاملA N-(2-aminophenyl)-5-(dimethylamino)-1-naphthalenesulfonic amide (Ds-DAB) based fluorescent chemosensor for peroxynitrite.
A dansyl derivative (Ds-DAB) was prepared and used as a fluorescent probe for peroxynitrite (ONOO(-)) detection. The results showed that the addition of peroxynitrite to the aqueous solution of Ds-DAB would result in obvious fluorescence enhancement. This probe is highly specific for peroxynitrite in aqueous solution, avoiding interference from other reactive oxygen species (ROS) and nitrogen s...
