Hg2+ detection using a phosphorothioate RNA probe adsorbed on graphene oxide and a comparison with thymine-rich DNA
(Royal Society of Chemistry, 2016-06-21)Mercury is a highly toxic heavy metal and many DNA-based biosensors have been recently developed for Hg2+ detection in water. Among them, thymine-rich DNA is the most commonly used for designing Hg2+ sensors. However, the ... -
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 ...
