Comparison of MoS2, WS2, and Graphene Oxide for DNA Adsorption and Sensing
(American Chemical Society, 2017-01-17)Interfacing DNA with two-dimensional (2D) materials has been intensely researched for various analytical and biomedical applications. Most of these studies have been performed on graphene oxide (GO) and two metal ... -
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 ... -
DNA Adsorption by ZnO Nanoparticles near Its Solubility Limit: Implications for DNA Fluorescence Quenching and DNAzyme Activity Assays
(American Chemical Society, 2016-06-07)Zinc oxide (ZnO) is a highly important material, and Zn2+ is a key metal ion in biology. ZnO and Zn2+ interconvert via dissolution and hydrolysis/condensation. In this work, we explore their interactions with DNA, which ... -
A highly specific sodium aptamer probed by 2-aminopurine for robust Na+ sensing
(Oxford University Press, 2016-09-20)Sodium is one of the most abundant metals in the environment and in biology, playing critical ecological and physiological roles. Na+ is also the most common buffer salt for nucleic acids research, while its specific ... -
Liposome/Graphene Oxide Interaction Studied by Isothermal Titration Calorimetry
(American Chemical Society, 2015-03-15)The interaction between graphene oxide (GO) and lipid bilayers is important for fundamental surface science and many applications. In this work, isothermal titration calorimetry (ITC), cryo-TEM, and fluorescence spectroscopy ... -
Molecularly Imprinted Polymers with DNA Aptamer Fragments as Macromonomers
(American Chemical Society, 2016-03-16)Molecularly imprinted polymers (MIPs) are produced in the presence of a template molecule. After removing the template, the cavity can selectively rebind the template. MIPs are attractive functional materials with a low ... -
Reversible gating of ion transport through DNA-functionalized carbon nanotube membranes
(Royal Society of Chemistry, 2017-01-03)Carbon nanotubes (CNTs) can be used to create unique fluidic systems for studying ion transport in nanochannels due to their well-defined geometry, atomically smooth and chemically inert surface, and similarity to transmembrane ...
