Abstract:

The influence of inertial effects on the fluorescence anisotropy r is discussed.From recent work on the anisotropy of a prolate fluorescent molecule in a liquid solvent it is known that its estimated experimental moment of inertia is as much as about 3 orders of magnitude greater than that calculated from its geometry.In this paper, by using a non-exponential form of the memory function K (t) in the generalized relaxation equation for r (t), a satisfactory agreement between measured and calculated moments of inertia is obtained.

Abstract:

Previous studies of protein oligomerization using time-resolved fluorescence anisotropy assumed a single fixed probe per oligomeric complex and an identical probe orientation in complexes of different stoichiometry. However, an oligomer consisting of “n” singly labeled monomers must necessarily have “n” probes. Moreover, in the expression for the anisotropy decay, the molecular axes from which the probe orientation is defined are different for complexes that differ in stoichiometry. Here, we derive an expression for the decay of the anisotropy for molecules with any number of fixed probes, and

Abstract Excitation anisotropy spectra of indole were measured in poly (vinyl alcohol) film at room temperature. The behaviour of the phosphorescence anisotropy of indole in isotropic and anisotropic PVA film enabled a conclusion to be drawn that the T1 - S0 transition is located outside the indole ring plane, close to the perpendicular direction.

Abstract:

UV-illumination of phase-separated surfactant films prepared from mixtures of photopolymerizable 10,12-pentacosadiynoic acid and perfluorotetradecanoic acid results in the formation of fluorescent polydiacetylene fibers and aggregates. In this work, the orientation of polymer strands that comprise the resulting photopolymer structures has been probed using fluorescence anisotropy imaging in combination with defocused single-molecule fluorescence imaging. Imaging experiments indicate the presence of significant fiber-to-fiber heterogeneity, as well as anisotropy within each fiber (or aggregate)

Abstract:

The fluorescence anisotropy of photosensitizers Radachlorin and chlorin e6 was studied using the time-resolved single photon-counting technique under one- and two-photon excitation within the Soret absorption band. A very small negative anisotropy was observed in both photosensitizers under one-photon excitation in the vicinity of the absorption maximum within the wavelength range of 395–405 nm. Meanwhile, two-photon excitation of the photosensitizers in the same spectral range demonstrated high fluorescence anisotropy with the maximum value of about 0.43.

Abstract:

Fluorescence anisotropy, a technique to study the folding state of proteins or affinity of ligands, is used in this present work as a temperature sensor, to measure the microfluidic temperature field, by adding fluorophore in the liquid. Fluorescein was used as a temperature-sensing probe, while glycerol–aq. ammonia solution was used as a working fluid. Fluorescence anisotropy of fluorescein was measured by varying various parameters. Apart from this, a comparison of fluorescence anisotropy and fluorescence intensity is also performed to demonstrate the validity of anisotropy to be applied in

Abstract:

Red blood cell (RBC) aggregation and deformation are governed by the molecular processes occurring on the membrane. Since several social important diseases are accompanied by alterations in RBC aggregation and deformability, it is important to develop a diagnostic parameter of RBC membrane structural integrity and stability. In this work, we propose membrane microviscosity assessed by time-resolved fluorescence anisotropy of the lipophilic PKH26 fluorescent probe as a diagnostic parameter. We measured the fluorescence decay curves of the PKH26 probe in the RBC membrane to establish the optimal

Fluorescence anisotropy and intensity decay experiments on proteins can provide detailed information on biomolecule dynamics and function. However, experiments of this sort are normally performed while the biomolecule is at or near equilibrium. Although information on protein dynamics under equilibrium conditions is extremely important, details about the protein behavior while it is actually undergoing change can provide significantly more insight into the overall protein behavior.
