Aptamer-Functionalized Hydrogel Microparticles for Fast Visual Detection of Mercury(II) and Adenosine
(American Chemical Society, 2012-04-25)With a low optical background, high loading capacity, and good biocompatibility, hydrogels are ideal materials for immobilization of biopolymers to develop optical biosensors. We recently immobilized mercury and lead binding ... -
Dissecting the effect of anions on Hg2+ detection using a FRET based DNA probe
(Royal Society of Chemistry, 2012-08-07)Many biosensors have been developed to detect Hg2+ using thymine-rich DNA. While sensor response to various cations is often studied to demonstrate selectivity, the effect of anions has been largely overlooked. Anions may ... -
DNA stabilized silver nanoclusters for ratiometric and visual detection of Hg2+ and its immobilization in hydrogels
(Elsevier, 2013-04-11)DNA oligomers are particularly interesting templates for making silver nanoclusters (AgNCs) as different emission colors can be obtained by varying the DNA sequence. Many AgNCs have been used as Hg2+ sensors since Hg2+ ... -
Metal-Induced Specific and Nonspecific Oligonucleotide Folding Studied by FRET and Related Biophysical and Bioanalytical Implications
(Wiley, 2012-01-13)Metal induced nucleic acid folding has been extensively studied with ribozymes, DNAzymes, tRNA and riboswitches. These RNA/DNA molecules usually have a high content of double-stranded regions to support a rigid scaffold. ...
