G-Quadruplex DNA for Fluorescent and Colorimetric Detection of Thallium(I)
(American Chemical Society, 2016-02-26)Thallium is a highly toxic heavy metal, but its 495 nm FRET sensing is underexplored compared to its neighboring elements Blue in the periodic table: lead and mercury. Thallium has two " oxidation states. A DNAzyme-based ... -
In Vitro Selection of a DNAzyme Cooperatively Binding Two Lanthanide Ions for RNA Cleavage
(American Chemical Society, 2016-05-03)Trivalent lanthanide ions (Ln(3+)) were recently employed to select RNA-cleaving DNAzymes, and three new DNAzymes have been reported so far. In this work, dysprosium (Dy3+) was used with a library containing 50 random ... -
In Vitro Selection of Chromium-Dependent DNAzymes for Sensing Chromium(III) and Chromium(VI)
(Wiley, 2016-07-04)Chromium is a very important analyte for environmental monitoring, and developing biosensors for chromium is a long-standing analytical challenge. In this work, in vitro selection of RNA-cleaving DNAzymes was carried out ... -
A Selective Na+ Aptamer Dissected by Sensitized Tb3+ Luminescence
(Wiley, 2016-08-17)A previous study of two RNA-cleaving DNAzymes, NaA43 and Ce13d, revealed the possibility of a common Na+ aptamer motif. Because Na+ binding to DNA is a fundamental biochemical problem, the interaction between Ce13d and Na+ ... -
A Silver DNAzyme
(American Chemical Society, 2016-04-05)Silver is a very common heavy metal, and its detection is of significant analytical importance. DNAzymes are DNA-based catalysts; they typically recruit divalent and trivalent metal ions for catalysis. Herein, we report a ...
