杆状病毒近晶层自扩散

Self-diffusion of Rod-like Viruses Through Smectic Layer

M. Paul Lettinga, Eric Grelet

摘要:

我们报告的直接可视化在近晶层之间的质量传输的单个颗粒的规模,也称为渗透,在杆状病毒的悬浮液。自扩散优先发生在垂直于近晶层的方向上,并且通过一个棒长度的准量子化步骤发生。扩散速率对应于从具有实验获得的层状周期性有序势的双稳态中的扩散计算的速率。

英文摘要:

We report the direct visualization at the scale of single particles of mass transport between smectic layers, also called permeation, in a suspension of rod-like viruses. Self-diffusion takes place preferentially in the direction normal to the smectic layers, and occurs by quasi-quantized steps of one rod length. The diffusion rate corresponds with the rate calculated from the diffusion in the nematic state with a lamellar periodic ordering potential that is obtained experimentally.
