Detection of Nitroaromatic Compounds through Fluorescence Quenching of Pyrene Labeled Starch Nanoparticles
Patel, Sanjay (University of Waterloo, 2018-12-10)The aim of this research was to demonstrate the potential application of starch nanoparticles (SNPs) labeled with 1-pyrenebutyric acid (PBA) as the active component in optical sensors used for the detection of minute ... -
Detection of Nitroaromatics Using the Excimer Fluorescence of Pyrene-Labeled Starch Nanoparticles
Patel, Sanjay; Seet, Jonathan; Li, Lu; Duhamel, Jean (American Chemical Society, 2019-09-09)Starch nanoparticles (SNPs) were hydrophobically modified using 1-pyrenebutyric acid (PyBA) with degrees of substitution (DS) between 0.0006 and 0.11. Fluorescence quenching studies were conducted on the pyrene-labeled ... -
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 ...
