Fig. 6. (a) Schematic diagram of the DSPE molecule showing directions of the transition dipole moments of the symmetric (νs(CH2)) and asymmetric (νas(CH2)) methylene stretches for a lipid acyl chain as well as the tilt angle (θchain) of acyl chains [adapted from ref. 42]. (b) The tilt angle of lipid acyl chains as a function of potential for the fBLM (curve 1), fBLM-AβM (curve 2) and fBLM-AβO (curve 3) in PBS/D2O (0.01 M phosphate buffer, 0.0027 M KCl and 0.137 M NaCl, pH = 7.4) solution. The upper abscissa plots the transmembrane potential that accounts for the potential of zero free charge (Epzfc = 0.11 V vs. Ag/AgCl).
