Abstract
Abstract Di-4-ANEPPS is a dye molecules which has been used to probe membrane electric potentials by its electrochromic response. The dye has an unusual blue shift in the absorption spectrum upon partitioning to lipid membranes. We studied its binding properties to membranes by absorption, fluorescence and resonance Raman spectroscopy. The latter technique provided evidence for the differential solubilization of the dye in the membrane, where the polar head of the molecule protrudes out of the lipid environment and is responsible for the spectral behavior.
