Fluoranthene tracer was selected to investigate the fluorescence quenching
in solution and in TSE because the UV light source for the fluorescence measurement system installed at the die has the highest radiation intensity at 365 nm at which fluoranthene is excited and emits the strongest fluorescence emission.
Discrimination of the photochemical and non-photochemical components of Chl fluorescence quenching
is critical to a full understanding of PSII functioning under continuous light, as we will see below.
5) Reduction of fluorescence was caused by increased hydrophobicity of the coating, which facilitated oxygen diffusion into the layer and enhanced oxygen-based fluorescence quenching
of the complex.
We monitored the change in fluorescence intensity as oxygen was allowed to diffuse into the film and the presence of oxygen was detected through measurements of fluorescence quenching
The team named their new technique fluorescence quenching
For field screening at the parts-per-million level, room temperature fluorescence appears satisfactory, since fluorescence quenching
by the internal heavy atom effect is not complete.
The mechanism of the fluorescence quenching
process was then carefully analyzed using Stern-Volmer equation: [I.
For fluorescence quenching
experiments, Stern-Volmer's equation was used (Eq.
Homogeneous time-resolved fluorescence quenching
assay (TruPoint) for nucleic acid detection.
6b) when compared with the nonirradiated sample, and this effect probably arises from a diminishing collision-induced fluorescence quenching
As lifetime change is an indicator of fluorescence quenching
, the longer lifetime of lanthanide chelates indicated less fluorescence quenching
with the surface-coated nanoparticles.
of polyaromatic molecules by electron deficient molecules was extensively studied in liquid solutions and both dynamic (collisional) and static fluorescence quenching
mechanisms were developed [1-3].
