这篇简短的评论讨论了理论和计算物理学以及实验工作对理解受限几何形状和液晶界面中胶体颗粒行为的最新贡献。概述了用于研究捕获、长程和短程相互作用以及固体颗粒和液体包裹体组装的理论方法。作为一个例子，一个球形胶体粒子与向列-各向同性界面的相互作用和两个胶体之间的对相互作用势在这个界面上通过最小化的Landau-de Gennes自由能泛函使用有限元方法与自适应网格。
This mini-review discusses the recent contribution of theoretical and computational physics as well as experimental efforts to the understanding of the behavior of colloidal particles in confined geometries and at liquid crystalline interfaces. Theoretical approaches used to study trapping, longand short-range interactions, and assembly of solid particles and liquid inclusions are outlined. As an example, an interaction of a spherical colloidal particle with a nematic-isotropic interface and a pair interaction potential between two colloids at this interface are obtained by minimizing the Landau-de Gennes free energy functional using the finite-element method with adaptive meshes.
