(Snapshots from the simulations). Simulation snapshot showing positions of multivalent ions in and outside the model VLP for (a) divalent cations (shown as small blue spheres) and (b) tetravalent anions (shown as small green spheres) for fixed σ1 = 0 and other parameter values given in Fig. 2. For the sake of illustration, the upper half of the outer shell (shown schematically as a red transparent sphere) and the NP coating layer (shown as a thick blue shell) are removed in the picture, while the core metallic NP is shown in whole (yellow sphere).
