Detection of Mercury by a Label-free Aptamer-based Fluorescent Assay
In this paper, a rapid fluorescence assay for the detection of mercury ions was developed using mercury-specific aptamer and PicoGreen, a fluorescent dye embedded in double helix DNA. Mercury ion concentration was determined by fluorescence signal intensity, and the linear relationship between the logarithm of mercury ion concentration and fluorescence intensity was obtained. The linear range of the method was 0.001-100 µg/mL, and the detection limit was 0.38 ng/mL. In the presence of interference ions such as As,3+,, Pb,2+,, Cd,2+,, Cr,2+,, K,+,, it has a good specificity. Meanwhile, the irrigation water samples with different concentrations of Hg,2+, showed a good recovery of 95.2%-97.9% and the relative standard deviation of 2.3%-4.0%. The method is simple, rapid and sensitive, and is applicable for the determination of mercury ions by using aptamer and fluorescent dye.
