WebWhen imaging multiple fluorophores in widefield fluorescence microscopy, bleed-through artifacts can often be overcome by the judicious choice of filter combinations. In addition to considering the emission spectral overlap of fluorophores, cross-excitation due to overlapping absorption bands must also be addressed. WebApr 8, 2024 · Fluorophore molecules primarily follow the conditions such as dipole orientation, distance, spectra, spectral overlapping, and lifetime of the donor for the occurrence of FRET to occur. FRET can only occur if the distance between donor fluorophore and acceptor is within the 1–10 nm range.
