Synthesis and Characterization of Two Pyrene Labeled Gemini Surfactants and their Interactions with Oppositely Charged Molecules
(University of Waterloo, 2022-06-09)Cationic gemini surfactants (GS) have attracted the attention of the scientific community as potential carriers of genetic cargo for gene transfection applications. These GS/polynucleotides complexes have been extensively ... -
Synthesis and Study of the Cyclic Lipopeptide Antibiotics Paenibacterin and Daptomycin
(University of Waterloo, 2021-09-23)Cyclic lipopeptides present a rich source of antimicrobial compounds with diverse modes of action. Paenibacterin is a cyclic lipopeptide antibiotic produced by Paenibacillus thaminolyticus that exhibits activity against a ... -
Temperature Response of Aqueous Solutions of Pyrene End-Labeled Poly(N-isopropyl acrylamide)s Probed by Steady-State and Time-Resolved Fluorescence
(Wiley, 2018-02-15)Aqueous solutions of a series of monodisperse poly(N‐isopropylacrylamide)s end‐labeled with n‐butyl‐1‐pyrene at one or both chain ends (Pyn‐PNIPAMs with n = 1 or 2) were studied by turbidimetry, light scattering, and ... -
Thioflavin T fluorescence and NMR spectroscopy 1 suggesting a non-G-quadruplex structure for a 2 sodium binding aptamer embedded in DNAzymes
(Canadian Science Publishing, 2021-09-16)Recently, a Na+-binding aptamer was reported to be embedded in a few RNA-cleaving DNAzymes including NaA43, Ce13d and NaH1. These DNAzymes require Na+ for activity but show no activity in the presence of K+ or other metal ... -
Towards understanding of poly-guanine activated fluorescent silver nanoclusters
(Institute of Physics, 2014-03-18)It has been recently reported that the fluorescence of some DNA-templated silver nanoclusters (AgNCs) can be significantly enhanced upon by hybridizing with a partially complementary DNA containing a G-rich overhang near ... -
Using Pyrene to Probe Interparticle Polymer Diffusion in a Latex Film
(University of Waterloo, 2015-12-16)Fluorescence has been used for many years as a powerful analytical tool to probe the formation of films from aqueous latex dispersions. Currently, the most widely used method is fluorescence resonance energy transfer (FRET), ...
