微粒在脂质膜上的吸附对于生物医学应用是至关重要的。重力对过程的影响长期以来被忽视。一个组合的直立和倒置的配置测量被开发来展示重力引起的颗粒吸附在膜上的介质的不同高度之间的差异。在相同的重力作用下，纳米粒子聚集体的吸附趋势比纳米粒子更均匀，这是由于纳米粒子聚集体的流体力学直径较大，导致浓度差异较小。
Particle adsorption on lipid membrane is critical to biomedical applications. Gravity effect on the process has long been ignored. A combination of the upright and inverted configuration measurements was developed to exhibit that gravity causes a particle adsorption disparity on membrane between the different heights of medium. The more homogeneous adsorption tendency of nanoparticle aggregate compared to nanoparticle under the same gravitational motive force is attributed to the larger hydrodynamic diameter induced lower concentration disparity.
