| Abstract Scope |
Rapid and reliable detection of Hg2+ is of great technical interest for environmental protection . In this study, a highly fluorescent, Hg2+ sensitive, and selective fluorometric assay was developed using vancomycin functionalized and polyethyleneimine stabilized gold nanoparticles. The vancomycin functionalized gold nanoparticles were highly fluorescent, with excitation and emission maxima occurring at 320 and 418 nm, respectively. The size of nanoparticles was to the order of 5-7 nm. The XRD analysis confirmed that the nanoparticles possessed crystalline structure with face centerd cubic symmetry. As made fluorescent gold showed the detection limit in a natural environmental sample to the order of 12.5 nM with highly selectivity toward mercury (II) cations among tested other divalent cations. |
