Photoswitching Mechanism of Cyanine Dyes
Cyanine dyes have been shown to undergo reversible photoswitching, where the fluorophore can be switched between a fluorescent state and a dark state upon illumination at different wavelengths. The photochemical mechanism by which switching occurs has yet to be elucidated. In this study, we have determined the mechanism of photoswitching by characterizing the kinetics of dark state formation an...
متن کاملAbnormal fluorescence behavior of some cyanine dyes in a cyanine dye–TiO colloids system
The absorption and fluorescence spectra of five typical cyanine dyes adsorbed on the surface of TiO colloids have been 2 studied. The absorption spectra show that there are two kinds of isomer produced by intramolecular torsional motion of these dyes in their ground states. The fluorescence quantum yields of these dyes may be enhanced or reduced in the presence of TiO colloids. This behavior ca...
متن کاملRigid cyanine dye nucleic acid labels.
Cyanine dyes attached to DNA via a rigid linker show useful fluorescence and FRET properties without altering the stability of duplex DNA.
متن کاملCounterion effects in cyanine heterojunction photovoltaic devices
We investigated cyanine heterojunction photovoltaic devices using carbocyanine dyes as donors and buckminsterfullerene (C60) as acceptor. In particular, we focused on the influence of cyanine counterions on the photovoltaic device characteristics. It was found that counterions can be displaced in the applied electric field and give rise to important hystereses in the current-voltage characteris...
متن کاملWater-soluble pyrrolopyrrole cyanine (PPCy) NIR fluorophores.
Water-soluble derivatives of pyrrolopyrrole cyanines (PPCys) have been synthesized by a post-synthetic modification route. In highly polar media, these dyes are excellent NIR fluorophores. Labeling experiments show how these novel dyes are internalized into mammalian cells.
