Red edge excitation shift of a deeply embedded membrane probe: implications in water penetration in the bilayer

Article Abstract:

Research concerning localization of the same fluorescent group at different bilayer depths to exhibit the solvent-induced effects has been conducted. Results demonstrate that NBD-cholesterol reveals strong fluorescence polarization dependence on excitation wavelength in fluid membranes.
