We therefore employ our previously developed computational model to confirm that these mechanisms emerge naturally from our proposed interaction potential. We perform simulations of 210 nm and 170 nm particles interacting via a pair potential that accounts for the combination of surface charge and polymer brush coating on the particles used in the experiment (details in Methods). As described throughout the rest of this article, these simulations recapitulate crystallization via a two-step process and subsequent crystal growth through Ostwald ripening and blob absorption, both on surfaces and in bulk, depending on the particle concentration and solution salt concentration.
