Hydrophobic Engineering of a Bacterial Nanodimensional Capsule Protein
(University of Waterloo, 2017-07-07)Recently, numerous protein-based nanomedicine platforms have been intensively explored. These systems are usually composed of self-assembling proteins that form controllable systems with different shapes and types. A ... -
Hydrophobic Modification of Starch
(University of Waterloo, 2019-08-27)Starch is a very common polysaccharide with multiple applications in the industry, but the range of physical properties exhibited by that material is relatively limited due to its strongly hydrophilic character. The work ... -
Identification of functional regions of streptococcus agalactiae CAMP factor
(University of Waterloo, 2008-09-26)Streptococcus agalactiae CAMP factor is a protein exotoxin that contains 226 amino acid residues and forms oligomeric pores on susceptible cell membranes and liposomes. In this study, fragments of CAMP factor were created ... -
Identifying Fenton-Reacted Trimethoprim Transformation Products Using Differential Mobility Spectrometry
(ACS Publications, 2018-04-17)A transformation product of trimethoprim, a contaminant of emerging concern in the environment, is generated using an electro-assisted Fenton reaction and analyzed using differential mobility spectrometry (DMS) in combination ... -
Immature SOD1: protein folding, misfolding and aggregation
(University of Waterloo, 2023-01-25)Protein misfolding and aggregation are hallmarks of many diseases, including amyotrophic lateral sclerosis (ALS). In familial ALS, aberrant self-association of mutant Cu,Zn-superoxide dismutase (SOD1) is implicated as a ... -
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) ... -
Immunoaffinity Solid Phase Microextraction
(University of Waterloo, 2007-12-18)Biological fluids are commonly analyzed in clinical and forensic studies for drug concentration measurements. Conventional quantification procedures are always associated with lengthy sample pretreatment steps to eliminate ... -
Impact of Single-Walled Carbon Nanotubes on Ciliated Protozoa & Bacteria
(University of Waterloo, 2009-02-02)As pointed out more and more frequently in the literature, there is a pressing need for research into the health and environmental impact of nanoparticles. This work represents a joint effort between scientists in ... -
