Large-Scale Assembly of NPs. So far, we have developed a many-body potential for polymer-grafted NPs of specific grafting density and showed that the potential can correctly capture the tendency of a small system of such NPs to assemble into string-like structures. We next used this potential to study the behavior of much larger systems of NPs, allowing us access to more realistic assembly morphologies formed by such NPs. At the same time, we also developed many-body potentials for other NP grafting conditions and used larger systems of those NPs to explore other assembly morphologies.
