Quantum Dots (QD-Dye Conjugate) are Ideal Candidates for FRET Investigations Using TIRMicroscopy [PDF]

Engineering and Technology Journal, 2014
Total Internal Reflection Microscopy has been employed to investigate Förster resonance energy transfer FRET for QD-dye conjugate system. QDs based donor systems are ideal for FRET for many reasons, one of them is that their broad excitation cross ...

Förster resonance energy transfer photoacoustic microscopy [PDF]

Journal of Biomedical Optics, 2012
Förster, or fluorescence, resonance energy transfer (FRET) provides fluorescence signals sensitive to intra- and inter-molecular distances in the 1 to 10 nm range. Widely applied in the fluorescence imaging environment, FRET enables visualization of physicochemical processes in molecular interactions and conformations.

Photoexcitation dynamics and energy engineering in supramolecular doping of organic conjugated molecules

Light: Science & Applications, 2023
The supramolecular coordination doping/blending allow for intermolecular Förster resonance energy transfer (FRET) and intramolecular charge transfer (ICT) in doping/blending films, endowing films with tunable bandgap, high PLQY and high conductivity.

Ultramarine, a chromoprotein acceptor for Förster resonance energy transfer. [PDF]

PLoS ONE, 2012
We have engineered a monomeric blue non-fluorescent chromoprotein called Ultramarine (fluorescence quantum yield, 0.001; ε(585 nm), 64,000 M(-1) x cm(-1)) for use as a Förster resonance energy transfer acceptor for a number of different donor fluorescent

Direct Interaction of Avian Cryptochrome 4 with a Cone Specific G-Protein

Cells, 2022
Background: Night-migratory birds sense the Earth’s magnetic field by an unknown molecular mechanism. Theoretical and experimental evidence support the hypothesis that the light-induced formation of a radical-pair in European robin cryptochrome 4a ...

Deep-tissue photoacoustic tomography of Förster resonance energy transfer [PDF]

Journal of Biomedical Optics, 2013
Förster resonance energy transfer (FRET) is a distance-dependent process that transfers excited state energy from a donor molecule to an acceptor molecule without the emission of a photon. The FRET rate is determined by the proximity between the donor and the acceptor molecules; it becomes significant only when the proximity is within several ...

Förster resonance energy transfer outpaces Auger recombination in CdTe/CdS quantum dots-rhodamine101 molecules system upon compression

Optics Express, 2021
Förster resonance energy transfer (FRET) and Auger recombination in quantum dots (QDs)-molecules system are important mechanisms for affecting performance of their optoelectronic and photosynthesis devices. However, exploring an effective strategy to promote FRET and suppress Auger recombination simultaneously remains a daunting challenge.

Tropomyosin Dynamics in Cardiac Thin Filaments: A Multisite Förster Resonance Energy Transfer and Anisotropy Study [PDF]

Biophysical Journal, 2008
Cryoelectron microscopy studies have identified distinct locations of tropomyosin (Tm) within the Ca(2+)-free, Ca(2+)-saturated, and myosin-S1-saturated states of the thin filament. On the other hand, steady-state Förster resonance energy transfer (FRET) studies using functional, reconstituted thin filaments under physiological conditions of ...
