  • Title: Visual detection of mercury(II) based on recognition of the G-quadruplex conformational transition by a cyanine dye supramolecule.
    Author: Chen H, Zhang X, Sun H, Sun X, Shi Y, Xu S, Tang Y.
    Journal: Analyst; 2015 Nov 07; 140(21):7170-4. PubMed ID: 26359517.
    Abstract:
    A supramolecular probe for visual detection of mercury (Hg) has been designed by using a cyanine dye and AS1411 G-quadruplexes, which exhibits an obvious color change from red to blue in response to an increased level of Hg(2+). The supramolecular probe exhibits high selectivity and sensitivity towards Hg(2+) and is promising for the detection of environmental samples with the naked eye.
