A Cleavable Molecular Beacon for Hg2+ Detection based on Phosphorothioate RNA Modifications
(American Chemical Society, 2015-06-10)Mercury is a highly toxic heavy metal, and detection of Hg2+ by biosensors has attracted extensive research interest in the past decade. In particular, a number of DNA-based sensing strategies have been developed. Well-known ... -
Contaminants and Nutrients in Traditional Food Fishes in Kluane Lake, YT
(2016-06)The outcomes of a collaborative project led by the Kluane First Nation (KFN), in partnership with the Arctic Institute of Community-Based Research (AICBR), the University of Waterloo, and Western University, are presented ... -
Control of mercury and methylmercury in contaminated sediments using biochars: A long-term microcosm study
(Elsevier, 2018-05-01)The effectiveness of activated carbon and four types of biochar, switchgrass (300 °C and 600 °C), poultry manure (600 °C), and oak (∼700 °C) with respect to mercury (Hg) and methylmercury (MeHg) control was assessed in ... -
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 ... -
Evaluation of mercury stabilization mechanisms by sulfurized biochars determined using X-ray absorption spectroscopy
(Elsevier, 2018-04-05)The application of biochar to treat mercury (Hg) in the environment is being proposed on an increasing basis due to its widespread availability and cost effectiveness. However, the efficiency of Hg removal by biochars is ... -
Field validation of DNA-based biosensor for rapid detection of ultra-trace mercury(II) in natural waters
(University of Waterloo, 2023-05-15)Mercury (Hg) remains a significant pollutant of global concern. In particular, contamination of surface water and groundwater by Hg poses severe threats, unrecognized in many cases, to the drinking water safety of numerous, ... -
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) ... -
Regenerable DNA-Functionalized Hydrogels for Ultrasensitive, Instrument-Free Mercury(II) Detection and Removal in Water
(American Chemical Society, 2010-09-15)Mercury is a highly toxic environmental pollutant with bioaccumulative properties. Therefore, new materials are required to not only detect but also effectively remove mercury from environmental sources such as water. We ...
