Figure 9: Long-time courses of (a) surface pressure, versus , and (b) electric surface potential, versus , owing to penetration of L-16-Y peptide to DPPG monolayers at various peptide concentrations (denoted therein). The initial surface pressure ( ) of pure DPPG monolayer was 30 ± 0.3 mN m−1 (typical of density of biomembranes).
