2-Aminopurine-modified DNA homopolymers for robust and sensitive detection of mercury and silver
(Elsevier, 2017-01-15)Heavy metal detection is a key topic in analytical chemistry. DNA-based metal recognition has advanced significantly producing many specific metal ligands, such as thymine for Hg2+ and cytosine for Ag+. For practical ... -
Conformation of Pyrene-Labeled Amylose in DMSO Characterized with the Fluorescence Blob Model
(American Chemical Society, 2016-10-25)Amylose and poly(methyl acrylate) were randomly labeled with pyrene to yield a series of Py-Amylose and Py-PMA constructs, and their ability to form excimer in DMSO was characterized quantitatively by steady-state and ... -
Covalent linking DNA to graphene oxide and its comparison with physisorbed probes for Hg2+ detection
(Elsevier, 2016-05-15)Graphene oxide (GO) has attracted extensive research interest as a platform for DNA adsorption and biosensor development. While most researchers use simple physisorption of fluorescently labeled DNA, covalent sensors are ... -
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 ... -
An Ultrasensitive Light-up Cu2+ Biosensor Using a New DNAzyme Cleaving a Phosphorothioate-Modified Substrate
(American Chemical Society, 2017-01-15)Cu2+ is a very important metal ion in biology, environmental science, and industry. Developing biosensors for Cu2+ is a key topic in analytical chemistry. DNAzyme-based sensors are highly attractive:, for their excellent ...
