Fig. 2: Stress asymmetry of tensionless bilayers for spherical nanovesicles with volume ν = ν0: leaflet tensions Σol (black squares) and Σil (blue circles) of the outer and inner leaflet as a function of the lipid number Nol assembled in the outer leaflet which implies the lipid number Nil = 10,100 − Nol in the inner leaflet.

Fig. 2

For 5400 ≤ Nol < 5963, the outer leaflet is stretched by the positive tension Σol whereas the inner leaflet is compressed by the negative tension Σil. Both leaflet tensions vanish for Nol = 5963. In all cases, the bilayer tension Σ = Σol + Σil (green diamonds) is close to zero. The numerical values for the volume ν0 as well as for the leaflet and bilayer tensions are provided in Table S1. Each data point represents the mean value over n = 15 statistically independent samples obtained from three replicated simulations. Each error bar is the standard error of the mean (SEM).
