Quantitative Characterization of Pyrene-Labeled Macromolecules in Solution by Global Analysis of Fluorescence Decays
(University of Waterloo, 2012-04-27)A series of pyrene end-labeled monodisperse poly(ethylene oxide)s (PEO(X)-Py2 where X represents the number average molecular weight (Mn) of the PEOs and equals 2, 5, 10 and 16.5 K) and one pyrene mono-labeled PEO (PEO(2K)-Py1) ... -
Selection and characterization of an aptamer to a thiazole orange derivative for use in a fluorescence-based biosensor
(University of Waterloo, 2023-08-18)Aptamers are short single-stranded DNA or RNA sequences that have been selected in vitro to have a high binding affinity to a specific target molecule. One class of aptamers can bind to small non-fluorescent molecules to ... -
Sensing guanine and its derivatives: From molecular recognition to applications
(Elsevier, 2020-11)Guanine plays an indispensable role in building nucleic acids, and its derivatives take part in various cellular functions such as regulating biological reactions and signal transduction. Monitoring the levels of guanine ... -
Study of Arborescent Poly(L-Glutamic Acid) by Pyrene Excimer Formation
(University of Waterloo, 2012-08-31)The biological function of a protein is determined by its amino acid sequence, structure, and internal dynamics. In turn the prediction of a protein structure from its folding pathway involves the characterization of the ... -
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), ...
