Examples of changes in the fluorescence spectra of 5M-PyIn-0 (A) and DMPmIn-0 (B) occurring upon titration with lipid vesicles. The enhancement of fluorescence is observed upon partitioning of the probe molecules in a lipid membrane. This enhancement is also accompanied by a blue shift of the emission maximum. The examples are shown for LUV composed of 25POPC/75POPG (see text). Concentration of the probes was 5–7 × 10−6 M, whereas the LUV concentration in the solution was varied from C = 0 to 2 mM. All the fluorescence spectra were measured in 50 mM sodium phosphate buffer at pH 8 with excitation at 313 nm. The spectra were corrected by subtracting scattering and background fluorescence.
