摘要
(Figure Presented) Going for gold! Thymine-Hg2+-thymine coordination is used as the basis for a selective assay that detects Hg 2+ ions with a limit of up to 0.2 parts per billion. The detection is based on the enhancement of fluorescence polarization (FP) by gold nanoparticles (see picture). The overall assay can be carried out at room temperature within only ten minutes, making it suitable for high-throughput routine applications in environment and food samples. © 2008 Wiley-VCH Verlag GmbH & Co.
