| 英文摘要 | A probe for colorimetric detecting lead ion (Pb2+) has been designed by using a newly synthesized clip-like cyanine dye and G-quadruplex. The unique structure of the clip-like cyanine dye endowed the probe with a high selectivity towards Pb2+. Significant changes in absorption spectra of the cyanine dye recognizing the Pb2+ -induced conformational transition of G-quadruplexes made the probe show a high sensitivity towards Pb2+ with a detection limit of 1 nM. The excellent performance enabled the probe to be practically applied in measuring the Pb2+ pollution in freshwater system. (C) 2015 Elsevier B.V. All rights reserved. |
