WebNov 15, 2024 · And these probes have exhibited small Stokes shift, which leads to high fluorescence interferences. Furthermore, only one probe among them is able to image NE in vivo successfully. To overcome the above problems, we designed a novel coumarin-based fluorescent probe HNCOU-NE with large Stokes shift to visualize NE activity in living cells … WebA fluorophore with a large Stokes shift will be much easier to use in your imaging then a fluorophore with a small Stokes shift. When there is only a small difference in wavelength between excitation and emission, it will be very difficult for you to see the emitted light from your labeled object as separate from the light used for excitation ...
Stokes shift is the difference (in energy, wavenumber or frequency units) between positions of the band maxima of the absorption and emission spectra (fluorescence and Raman being two examples) of the same electronic transition. It is named after Irish physicist George Gabriel Stokes. Sometimes Stokes shifts … See more Stokes fluorescence is the emission of a longer-wavelength photon (lower frequency or energy) by a molecule that has absorbed a photon of shorter wavelength (higher frequency or energy).
