  • Title: Silver(I) ions and cysteine detection based on photoinduced electron transfer mediated by cytosine-Ag(+)-cytosine base pairs.
    Author: Xie WY, Huang WT, Li NB, Luo HQ.
    Journal: Analyst; 2011 Oct 21; 136(20):4130-3. PubMed ID: 21863169.
    Abstract:
    Upon formation of cytosine-Ag(+)-cytosine base pairs as a mediator for the photoinduced electron transfer, the fluorescence of FAM-labeled DNA was quenched and the fluorescence emission wavelength exhibited a red shift. Based on these phenomena a novel dual-output fluorescent DNA sensor for Ag(+) ions and cysteine detection was developed.
