Performance of Biological Filters for Drinking Water Treatment and Their Use for High Pressure Membrane Biofouling Control
(University of Waterloo, 2016-01-18)Biofiltration is a promising green drinking water treatment technology that can reduce the concentration of biodegradable organic matter (BOM) in water. Direct biofiltration or biofiltration without pretreatment (BFwp) ... -
Pyrenyl Derivative with a Four-Atom Linker That Can Probe the Local Polarity of Pyrene-Labeled Macromolecules
(American Chemical Society, 2016-02-04)The fluorescent probe 1-pyrenemethoxyethanol (PyMeEGOH) was designed to replace commercially available 1-pyrenebutanol (PyButOH) as an alternative fluorescent label to probe the internal dynamics and interior polarity of ... -
Quantifying the Level of Intermacromolecular Interactions in Ethylene-Propylene Copolymers by Using Pyrene Excimer Formation
(American Chemical Society, 2015-07-14)A unique methodology based on fluorescence measurements is introduced to quantitatively measure the actual level of interpolymeric association between ethylene-propylene (EP) copolymers used as viscosity index improvers ... -
Quantitative Characterization of Polymeric Engine Oil Additives in Solution by Fluorescene
(University of Waterloo, 2015-08-24)The solution behavior of several polymeric oil additives has been characterized by using fluorescence. First, the chemical composition of the polyisobutylene-based dispersants was determined by using the inherent fluorescence ... -
Streptococcus agalactiae CAMP factor: Functional Roles of N- and C-terminal Domains & Target Membrane Effect on Toxin Activity
(University of Waterloo, 2018-05-22)CAMP factor is a well-known pore-forming toxin secreted by Streptococcus agalactiae that forms discrete pores on susceptible membranes whether natural or artificial. This work reports haemolysis and liposome permeabilization ... -
The Structure and Internal Dynamics of Polypeptides Probed with Pyrene Excimer Fluorescence
(University of Waterloo, 2021-01-25)A combination of pyrene excimer fluorescence, fluorescence blob model (FBM), and molecular mechanics optimizations (MMOs) was applied to characterize a series of pyrene-labeled polypeptides. Analysis of the fluorescence ... -
Thermodynamics and Kinetics of Adaptive Binding in the Malachite Green RNA Aptamer
(American Chemical Society, 2013-09-24)Adaptive binding, the ability of molecules to fold themselves around the structure of a ligand and thereby incorporating it into their three-dimensional fold, is a key feature of most RNA aptamers. The malachite green ... -
Two successive calcium-dependent transitions mediate membrane binding and oligomerization of daptomycin and the related antibiotic A54145
(Elsevier, 2016-09)Daptomycin and A54145 are homologous lipopeptide antibiotics that permeabilize the cell membranes of Gram-positive bacteria. Membrane permeabilization depends on the presence of both phosphatidylglycerol (PG) and calcium, ... -
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 ...
