WebFluorescence is a radiative process in which molecules (fluorophores) decay to the ground state by emitting detectable photons (on the timescale of 10−9 s 10 − 9 s ). The fluorescence emission happens from the lowest excited electronic level ( S1 S 1 ). WebFeb 28, 2024 · Researchers often apply the fusion of tags and fluorophores to viral proteins, surrogate proteins, or dyes to follow individual virus particles while they progress throughout infection. The inclusion of such fusion motifs or surrogates frequently disrupts viral infectivity or results in a change of the wild-type phenotype.
