Application of Pyrene Fluorescence to the Characterization of Hydrophobically Modified Starch Nanoparticles
Kim, Damin; Amos, Ryan; Gauthier, Mario; Duhamel, Jean (American Chemical Society, 2018-06-25)Several aspects of pyrene fluorescence were applied to gain an insight into the nature of the microdomains in hydrophobically modified starch nanoparticles (HM-SNPs), prepared by reacting SNPs with propionic and hexanoic ... -
Characterization of Hydrophobically Modified Starch Nanoparticles by Pyrene Fluorescence
Kim, Damin (University of Waterloo, 2017-01-25)Starch nanoparticles (SNPs) were hydrophobically modified with propionic (C3) and hexanoic (C6) anhydride via esterification. Different degrees of substitution (DS) of the hydroxyl groups of the SNPs were achieved by varying ... -
Characterization of the Conformation and Internal Backbone Dynamics of a-Polyglucans by Pyrene Excimer Fluorescence
Kim, Damin (University of Waterloo, 2021-11-23)The conformation and internal backbone dynamics (IBD) of several pyrene-labeled polysaccharides (Py-PSs), namely Py-Amylopectin, Py-Glycogen, Py-Dextran, and Py-Pullulan, were successfully examined with a combination of ... -
Surfactant-Structure Dependent Interactions with Modified Starch Nanoparticles Probed by Fluorescence Spectroscopy
Zhang, Qian; Kim, Damin; Li, Lu; Patel, Sanjay; Duhamel, Jean (American Chemical Society, 2019-02-05)The interactions between the surfactants sodium dodecyl sulfate (SDS) and sodium dioctylsulfosuccinate (AOT) and starch nanoparticles hydrophobically modified with the hydrophobic dye pyrene (Py-SNPs) were investigated in ...
