We next compared the assembly structures formed by the three NPs in simulations using and). Importantly, simulations using the two-body potential falsely predict the formation of a closed triangle with both initial configurations (Fig. and, right). In addition, we find that the many-body potential can accurately capture the second peak in the radial distribution function corresponding to string formation, whereas the two-body potential is unable to capture this peak (Fig. ). Thus, the many-body potential is not only able to reproduce the structures formed by polymer-grafted NPs but also the underlying assembly pathways.
