Characterization of glucose oxidation by gold nanoparticles using nanoceria
(Elsevier, 2014-04-30)Gold nanoparticles (AuNPs) can oxidize glucose, producing hydrogen peroxide and gluconic acid, which are the same products as those generated by glucose oxidase (GOx). In this regard, AuNPs are a nanozyme. Herein, a new ... -
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 ... -
Fast assembly of non-thiolated DNA on gold surface at lower pH
(Elsevier, 2013-12-01)In a typical protocol for attaching DNA to a gold electrode, thiolated DNA is incubated with the electrode at neutral pH overnight. Here we report fast adsorption of non-thiolated DNA oligomers on gold electrodes at acidic ... -
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 ... -
Oligonucleotide-functionalized hydrogels as stimuli responsive materials and biosensors
(Royal Society of Chemistry, 2011-08-07)Hydrogels are crosslinked hydrophilic polymers that undergo swelling in water. The gel volume is affected by many environmental parameters including temperature, pH, ionic strength, and solvent composition. Therefore, these ... -
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 ...
