Coherent cooperative fluorescence resonance energy transfer [PDF]
Optics and Spectroscopy, 2014 Cooperative fluorescence resonance energy transfer effect is experimentally demonstrated for a few crystals doped with rare-earth ions. We show that, at the liquid helium temperatures in similar crystals, coherent cooperative fluorescence resonance energy transfer, as well as an inverse coherent up-conversion process, could be observed, and briefly ...

Polarized Fluorescence Resonance Energy Transfer Microscopy [PDF]
Biophysical Journal, 2004 Current methods for fluorescence resonance energy transfer (FRET) microscopy of living cells involve taking a series of images with alternating excitation colors in separate camera exposures. Here we present a new FRET method based on polarization that requires only one camera exposure and thereby offers the possibility for better time resolution of ...

Influence of chirality on fluorescence and resonance energy transfer [PDF]
The Journal of Chemical Physics, 2019 Electronically excited molecules frequently exhibit two distinctive decay mechanisms that rapidly generate optical emission: one is direct fluorescence and the other is energy transfer to a neighboring component. In the latter, the process leading to the ensuing “indirect” fluorescence is known as FRET, or fluorescence resonance energy transfer.

Resonant Critical Coupling of Surface Lattice Resonances with Fluorescent Absorptive Thin Film [PDF]
J. Phys. Chem. C 127, 22212 (2023), 2023 Surface lattice resonance supported on nanoparticle arrays is a promising candidate in enhancing fluorescent effects in both absorption and emission. The optical enhancement provided by surface lattice resonance is primarily through the light confinement beyond the diffraction limit, where the nanoparticle arrays can enhance light-matter interaction ...

Fluorescence Resonance Energy Transfer Microscopy [PDF]
Microscopy Today, 2000 Abstract Fluorescence is a property of certain fluorophores, which allows them to absorb light at one wavelength and emit the light at another, longer wavelength. This fluorescence can be used as a tool to study the interactions of numerous components within a cell.

Fluorescence Resonance Energy Transfer in Polydiacetylene Liposomes [PDF]
The Journal of Physical Chemistry B, 2008 Conjugated polydiacetylene (PDA) possessing stimuli-responsive properties has been intensively investigated for developing efficient sensors. We report here fluorescence resonance energy transfer (FRET) in liposomes synthesized using different molar ratios of dansyl-tagged diacetylene and diacetylene-carboxylic acid monomers.

GPCRs Interaction Measurement by Fluorescence Resonance Energy Transfer (FRET)
Bio-Protocol, 2012 This is a protocol to determine the physical interaction of a G-protein coupled receptor (GPCR) with itself (homodimerization) or with other GPCR (heterodimerazation) using fluorescence resonance energy transfer (FRET).

Quantitative Imaging of Protein-Protein Interactions by Multiphoton Fluorescence Lifetime Imaging Microscopy using a Streak camera [PDF]
Journal of Biomedical Optics Vo.8, 362 (July 2003), 2003 Fluorescence Lifetime Imaging Microscopy (FLIM) using multiphoton excitation techniques is now finding an important place in quantitative imaging of protein-protein interactions and intracellular physiology. We review here the recent developments in multiphoton FLIM methods and also present a description of a novel multiphoton FLIM system using a ...
