To investigate how well the many-body potential developed here reproduced the assembly behavior of NPs treated using the original CG force field with explicit description of polymer grafts and matrix, we again considered polymer-grafted NPs with Γ = of 0.3 chains/𝜎 ! and carried out MD simulations of three such particles treated using the many-body potential 𝑈 )* (Eqs. 1-6) with parameters listed in Tables and. For comparison, we carried out MD simulations of the corresponding system treated using the CG force field as well as MD simulations using only two-body interactions of the many-body potential; we call this a two-body potential and it is denoted by
