Fluorescence Quantum Yields in Complex Environments from QM-MM TDDFT Simulations: The Case of Indole in Different Solvents
(American Chemical Society, 2020-11)
Fluorescence is commonly exploited to probe microscopic properties. An important example is tryptophan in protein environments, where variations in fluorescence quantum yield, and in absorption and emission maxima, are ...
Fluorescence Nanoscopy with Optical Sectioning by Two-Photon Induced Molecular Switching using Continuous-Wave Lasers
(Wiley VCH Verlag, 2008-02)
During the last decade far-field fluorescence microscopy methodshave evolved that have resolution far below the wavelength oflight. To outperform the limiting role of diffraction, all thesemethods, in one way or another, ...
Colour and surface fluorescence development and their relationship with Maillard reaction markers as influenced by structural changes during cornflakes production
(Elsevier, 2012-12)
The aim of this work was to study colour and surface fluorescence development in relation to the chemical markers for the Maillard reaction at the cooking, flaking and toasting stages of cornflake production process. Colour ...
Quantification of fluctuations from fluorescence correlation spectroscopy experiments in reaction-diffusion systems
(American Physical Society, 2020-11)
Fluorescence correlation spectroscopy (FCS) is commonly used to estimate diffusion and reaction rates. In FCS the fluorescence coming from a small volume is recorded and the autocorrelation function (ACF) of the fluorescence ...
Rate constants of quenching of the fluorescence of pterins by the iodide anion in aqueous solution
(Elsevier Science, 2012-07)
The fluorescence of various pterins (6-methylpterin, 6-hydroxymethylpterin, 6-formylpterin, and 6-carboxypterin) was quenched using iodide in neutral, aerated neutral phosphate buffer. Stern-Volmer plots and the fluorescence ...
Single Molecule Blinking and Photobleaching Separated by Wide-Field Fluorescence Microscopy
(American Chemical Society, 2005-08)
Single molecule fluorescence detection of Atto590 in poly(vinyl alcohol) was achieved by using a wide-field epifluorescence microscope with CCD-camera detection. Image sequences are obtained from which the time traces of ...
An improved signal-conservative approach to cope with Rayleigh and Raman signals in fluorescence landscapes
(Elsevier Science, 2019)
Fluorescence excitation-emission matrix spectroscopy coupled to multi-way analysis has proved to be a powerful tool for the study of complex systems with analytical purposes. However, scattering phenomena that are usually ...
Fluorescence sensors for imaging membrane lipid domains and cholesterol
(Elsevier Academic Press Inc., 2021-10)
Lipid membrane domains are supramolecular lateral heterogeneities of biological membranes. Of nanoscopic dimensions, they constitute specialized hubs used by the cell as transient signaling platforms for a great variety ...
Variability in chlorophyll fluorescence spectra of eggplant fruit grown under different light environments: A case study
(Royal Society of Chemistry, 2017-02)
The main goal of the present work was to clarify physiological strategies in plants whose chloroplasts were developed under different light environments. The specific objective was to elucidate the influence of the spectral ...
Photoswitchable fluorescent diheteroarylethenes: substituent effects on photochromic and solvatochromic properties
(Royal Society of Chemistry, 2014-01)
Photoswitchable fluorescent diheteroarylethenes are promising candidates for applications in super-resolution molecular localization fluorescence microscopy thanks to their high quantum yields and fatigue-resistant ...
