Exploring the Dynamics of Cell Processes through Simulations of Fluorescence Microscopy Experiments
(Cell Press, 2015-06)
Fluorescence correlation spectroscopy (FCS) methods are powerful tools for unveiling the dynamical organization of cells. For simple cases, such as molecules passively moving in a homogeneous media, FCS analysis yields ...
Imaging amyloid precursor protein in vivo: An axonal transport assay
(Humana Press, 2012-08)
Fusion of fluorescent probes to axonally transported proteins represents an established approach that enables live imaging of axonal transport. In this approach, in vivo examination of fluorescent particle dynamics provides ...
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 ...
DNA-protected silver emitters: Charge dependent switching of fluorescence
(Royal Society of Chemistry, 2017-02)
The relationship between the state of charge and spectroscopy of DNA-protected silver emitters is not yet well understood. This remains one of the major issues to unveil in order to fully disentangle the spectroscopic ...
Stress-induced decrement in the plasticity of the physical properties of chick brain membranes
(Taylor & Francis Ltd, 2002-07)
The molecular basis underlying the stress-induced increment in the density of central benzodiazepine receptor from chick forebrain, observed previously at 4°C, was studied from a biophysical perspective. The thermal ...
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 ...
Charge-transfer dynamics of fluorescent dye-sensitized electrodes under applied biases
(American Chemical Society, 2015-07)
The development of dye-sensitized solar cells requires an in-depth understanding of the interfacial charge-transfer dynamics that take place between dye sensitizers and semiconductors. Here, we describe a prototype system ...
Quantifying transcription factor binding dynamics at the single-molecule level in live cells
(Academic Press Inc Elsevier Science, 2017-07)
Progressive, technological achievements in the quantitative fluorescence microscopy field are allowing researches from many different areas to start unraveling the dynamic intricacies of biological processes inside living ...
Smoothed quantum-classical states in time-irreversible hybrid dynamics
(American Physical Society, 2017-09-22)
We consider a quantum system continuously monitored in time which in turn is coupled to an arbitrary dissipative classical system (diagonal reduced density matrix). The quantum and classical dynamics can modify each other, ...
Rich stochastic dynamics of co-doped Er:Yb fluorescence upconversion nanoparticles in the presence of thermal, nonconservative, harmonic and optical forces
(IOP Publishing, 2017-03)
The stochastic dynamics of individual co-doped Er:Yb upconversion nanoparticles (UCNP) were investigated from experiments and simulations. TheUCNPwere characterized by high-resolution scanning electron microscopy, dynamic ...
