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 ... -
A Membrane Biosensor for the Detection of Lactate in Body Fluids
(University of Waterloo, 2019-01-31)The increased demand of real-time and convenient heath monitoring has spurned the rapid development of wearable health monitoring devices. In these devices, the central part is the sensor that can convert health information ... -
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 ... -
Stabilizing DNA G-quadruplexes by thallium(I) and its application for thallium detection
(University of Waterloo, 2015-08-21)Heavy metals such as thallium are dangerous to living organisms and the environment. They are toxic and harmful. The threat of pollution from these metals is ever growing due to increased mining around the world. Thallium ... -
The Study of Carbon Nanotube based Chemi-resistive Portable Biosensors used for the Detection of Bacteria
(University of Waterloo, 2017-09-14)The successful fabrication and characterization of a portable, disposable single walled carbon nanotube biosensor used for the detection of bacteria was demonstrated by this work. The Si/SiO2 based SWNT growth using chemical ... -
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 ...
