Cr3+ Binding to DNA Backbone Phosphate and Bases: Slow Ligand Exchange Rates and Metal Hydrolysis
(American Chemical Society, 2017-06-07)The interaction between chromium ions and DNA is of great interest in inorganic chemistry, toxicology, and analytical chemistry. Most previous studies focused on in situ reduction of Cr(VI), producing Cr3+ for DNA binding. ... -
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 ... -
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 ...
