(b) In the schematic diagram of energy transfer between fluorescent fluorophores and NPs, there is no significant Stokes shift in the absorption and emission spectra of NPs (red), which is related to LSPR.

WebThe emission spectrum of the donor fluorophore must overlap the absorption spectrum of the acceptor fluorophore. The greater the degree of spectral overlap, the more likely FRET is to occur. Dipole orientation. Energy transfer from the donor fluorophore to the acceptor fluorophore occurs via intermolecular dipole-dipole coupling. 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 10, 2024 · So, the electron transfer is not the only factor for PL quenching rather another predominating factor is the energy transfer e.g. FRET and it is applicable if the emission spectra of donor fluorophore overlap with the absorbance spectra of acceptor molecule (nitro compounds). WebGFP could be a problem because its green signal overlaps with commonly used FAM dye in Taqman system. You can consider using Hex (red) to replace FAM for the probe.
