We study self-assembly on a spherical surface of a model for a binary mixture of amphiphilic dimers in the presence of guest particles via Monte Carlo (MC) computer simulation. All particles had a hard core, but one monomer of the dimer also interacted with the guest particle by means of a short-range attractive potential. We observed the formation of aggregates of various shapes as a function of the composition of the mixture and of the size of guest particles. Our MC simulations are a further step towards a microscopic understanding of experiments on colloidal aggregation over curved surfaces, such as oil droplets.
我们通过蒙特卡罗（MC）计算机模拟，研究了在存在客体粒子的情况下，两亲性二聚体二元混合物模型在球形表面上的自组装过程。所有粒子都有一个硬核，但二聚体的一个单体还通过短程吸引势与客体粒子相互作用。我们观察到，作为混合物组成和客体粒子大小的函数，形成了各种形状的聚集体。我们的MC模拟朝着从微观层面理解诸如油滴等弯曲表面上的胶体聚集实验又迈进了一步。
