In this article, we review both theoretical models and experimental results on the motion of micro- and nano- particles that are close to a fluid interface or move in between two fluids.

Viscous drags together with dissipations due to fluctuations of the fluid interface and its physicochemical properties affect strongly the translational and rotational drags of colloidal particles, which are subjected to Brownian motion in thermal equilibrium. Even if many theoretical and experimental investigations have been carried out, additional scientific efforts in hydrodynamics, statistical physics, wetting and colloid science are still needed to explain unexpected experimental results and to measure particle motion in time and space scales, which are not accessible so far.

在本文中，我们回顾了关于接近流体界面或在两种流体之间运动的微米和纳米粒子运动的理论模型和实验结果。

由于流体界面的波动，粘性阻力和耗散共同作用，其物理化学特性强烈影响胶体颗粒的平移和旋转阻力，而胶体颗粒在热平衡下会发生布朗运动。即使已经进行了许多理论和实验研究，仍然需要在流体力学，统计物理学，润湿和胶体科学方面做出额外的科学努力，以解释意想不到的实验结果并测量时间和空间尺度上的粒子运动，这是迄今为止尚无法获得的。 。
