FIGURE 2.

Adsorption of a spherical macroion (R_p = 10 Å) onto binary (PC/PS) lipid membranes with (a) Steady-state (equilibrium) adsorption free energy (in k_BT units) as a function of macroion-membrane separation calculated using our method (solid line) and by the method used in May et al. (20) (dashed line). (b) Time sequence of radial profiles of the local fraction of PS lipids, for macroion-membrane separation of h = 3 Å. The steady-state distribution of PS lipids from the calculations by May et al. is shown for comparison (dotted-dashed line).
