Comparison of Graphene Oxide and Reduced Graphene Oxide for DNA Adsorption and Sensing
(American Chemical Society, 2016-10-18)Fluorescently labeled DNA adsorbed on graphene oxide (GO) is a well-established sensing platform for detecting a diverse range of analytes. GO is a loosely defined material and its oxygen content may vary depending on the ... -
Degradable starch nanoparticle assisted ethanol precipitation of DNA
(Elsevier, 2014-04-18)Precipitation of DNA from a large volume of aqueous solution is an important step in many molecular biology and analytical chemistry experiments. Currently, this is mainly achieved by ethanol precipitation, where a long-term ... -
DNA stabilized fluorescent metal nanoclusters for biosensor development
(Elsevier, 2014-03-22)Fluorescent silver, gold and copper nanoclusters (NCs) have emerged for biosensor development. Compared to semiconductor quantum dots, there is less concern about the toxicity of metal NCs, which can be more easily conjugated ... -
Electrostatically Directed Visual Fluorescence Response of DNA-Functionalized Monolithic Hydrogels for Highly Sensitive Hg2+ Detection
(American Chemical Society, 2011-03-23)Hydrogels are cross-linked hydrophilic polymer networks with low optical background and high loading capacity for immobilization of biomolecules. Importantly, the property of hydrogel can be precisely controlled by changing ... -
Fluorescent sensors using DNA-functionalized graphene oxide
(Springer, 2014-07-02)In the past few years, graphene oxide (GO) has emerged as a unique platform for developing DNA-based biosensors, given the DNA adsorption and fluorescence-quenching properties of GO. Adsorbed DNA probes can be desorbed ... -
Immobilization of DNA on Magnetic Microparticles for Mercury Enrichment and Detection with Flow Cytometry
(Wiley, 2011-04-26)Mercury detection in water has attracted a lot of research interest due to its highly toxic nature and adverse environmental impact. In particular, the recent discovery of specific binding of HgII to thymine-rich (T-rich) ... -
Label-Free Ag+ Detection by Enhancing DNA Sensitized Tb3+ Luminescence
(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 ... -
Visual optical biosensors based on DNA-functionalized polyacrylamide hydrogels
(Elsevier, 2013-12-15)Biosensors are devices that can provide quantitative or semi-quantitative analytical information about target molecules, where molecular recognition is based on biomolecular interactions. In recent years, DNA has emerged ...
