Effect of nanoclay laponite and pH on the energy transfer between fluorescent dyes [PDF]
J Photochem Photobiol A 252 (2013) 174-182, 2014 Fluorescence resonance energy transfer (FRET) between two dyes acriflavine (Acf) and rhodamine B (RhB) were investigated in solution and Layer-by-Layer (LbL) self assembled films in presence and absence of clay mineral laponite. UV-Vis absorption and fluorescence spectroscopy studies suggest both the dyes present mainly as monomer in solution and films.

Two-photon fluorescence: Resonance energy transfer [PDF]
The Journal of Chemical Physics, 1998 Fluorescence resonance energy transfer (FRET) is a technique now widely applied to probe biological and other complex systems for the determination of fluorophore separation and structure. Recently the theory behind the anisotropy of fluorescence has been extended to include the case of a residual polarization following energy transfer between ...

Development of hard water sensor using Fluorescence Resonance Energy Transfer [PDF]
Sens Act B, 184 (2013) 268, 2014 A method is presented for the sensing of water hardness by determining the concentration of calcium and magnesium in water, based on Fluorescence resonance energy transfer (FRET) process. The principle of the proposed sensor is based on the change of FRET efficiency between two laser dyes Acriflavine (Acf) and Rhodamine B (RhB) in presence of permanent

ixFLIM: Interferometric Excitation Fluorescence Lifetime Imaging Microscopy [PDF]
arXiv, 2023 Fluorescence lifetime imaging microscopy (FLIM) is a well-established technique with numerous imaging applications. Yet, one of the limitations of FLIM is that it provides information about the emitting state only. Here, we present an extension of FLIM by interferometric measurement of fluorescence excitation spectra.

uFLIM -- Unsupervised analysis of FLIM-FRET microscopy data [PDF]
, 2021 Despite their widespread use in cell biology, fluorescence lifetime imaging microscopy (FLIM) data-sets are challenging to analyse, because each spatial position can contain a superposition of multiple fluorescent components. Here, we present a data analysis method employing all information in the available photon budget, as well as being fast.

Development of an Ion-Sensor using Fluorescence Resonance Energy Transfer [PDF]
Sensors and Actuators B Chemical 195 (2014) 382-388, 2014 A method is presented for the sensing of ions by determining the concentration of corresponding salts (KCl, NaCl, MgCl2, CaCl2, FeCl3, FeSO4, AlCl3) in water, based on Fluorescence resonance energy transfer (FRET) process. The principle of the proposed sensor is based on the change of FRET efficiency between two laser dyes Acriflavine and Rhodamine B ...
