Thickness of the surface layers and ellipsometric angles before and after interaction of REF and SRPP with PBS pH 7.4 as subphase.

N/A, not applicable.aLipid monolayers were formed at a constant pressure of 28 mN/m and at 25°C. REF and SRPP were injected at 1 µM in a PBS 1X buffer subphase.bEllipsometry angles |δΔ| and Ψ; |δΔ| = |Δ−Δ0|. Pressure was at the equilibrium state (less than 1 h), when the pressure values were at plateau.cThe thickness was determined using a mean value of 1.45 for the refractive index. Results are presented as mean ± SD. Corresponding ellipsometric images are presented in Figure 6b.
