Fluorescent Detection mercury & methylmercury using a fluorescent peptidyl probe using aggregation induced emission |
| 초록 |
A fluorescent peptidyl chemosensor for the detection of heavy metal ions in aqueous solution was synthesized on the basis of the peptide receptor for the metal ions using an aggregation-induced emission fluorophore. The peptidyl chemosensor bearing tetraphenylethylene fluorophore showed an exclusively selective turn-on response to Hg2+ & CH3Hg+ among 16 metal ions in aqueous buffered solution containing NaCl. The peptidyl chemosensor complexed Hg2+ & CH3Hg+ and then aggregated in aqueous buffered solution, resulting in the significant enhancement of emissions at around 470 nm. The fluorescent sensor showed a highly sensitive response to Hg2+, and about 1.0 equiv and 25 equiv of Hg2+ and CH3Hg+ was enough for the saturation of the emission intensity change, respectively. The association constant for 1:1 complex was calculated based on the titration curve of the probes with Hg2+. |
