G-Quadruplex DNA for Fluorescent and Colorimetric Detection of Thallium(I)

Hoang, Michael; Huang, Po-Jung Jimmy; Liu, Juewen (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 ...
Label-Free Ag+ Detection by Enhancing DNA Sensitized Tb3+ Luminescence

Kleinke, Kimberly; Saran, Runjhun; Liu, Juewen (Multidisciplinary Digital Publishing Institute, 2016-08-26)

In this work, the effect of Ag+ on DNA sensitized Tb3+ luminescence was studied initially using the Ag+-specific RNA-cleaving DNAzyme, Ag10c. While we expected to observe luminescence quenching by Ag+, a significant ...
A Selective Na+ Aptamer Dissected by Sensitized Tb3+ Luminescence

Zhou, Wenhu; Ding, Jinsong; Liu, Juewen (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+ ...
