Besides direct particle–particle interactions, nanoparticles adsorbed to biomembranes experience indirect interactions that are mediated by the membrane curvature arising from particle adsorption. In this Letter, we show that the curvature-mediated interactions of adsorbed Janus particles depend on the initial curvature of the membrane prior to adsorption, that is, on whether the membrane initially bulges toward or away from the particles in our simulations. The curvature-mediated interaction can be strongly attractive for Janus particles adsorbed to the outside of a membrane vesicle, which initially bulges away from the particles. For Janus particles adsorbed to the vesicle inside, in contrast, the curvature-mediated interactions are repulsive. We find that the area fraction of the adhesive Janus particle surface is an important control parameter for the curvature-mediated interaction and assembly of the particles, besides the initial membrane curvature.

膜囊泡上Janus纳米粒子的曲率介导组装。

除了直接的颗粒间相互作用外,吸附到生物膜上的纳米颗粒还经历了间接相互作用,这种相互作用是由颗粒吸附引起的膜曲率介导的。在这封信中,我们证明了吸附的Janus颗粒的曲率介导的相互作用取决于在吸附之前膜的初始曲率,即,在我们的模拟中,膜最初是否朝向或远离颗粒隆起。曲率介导的相互作用对于吸附到膜囊泡外部的Janus颗粒具有强烈的吸引力,该膜囊泡最初从颗粒中鼓出。相反,对于吸附在囊泡内部的Janus颗粒,曲率介导的相互作用是排斥的。
