论文摘要
我们考虑纳米通道表面起伏对其中颗粒运动的影响。我们报告了表面在纳米通道中向流体流动颗粒棘轮转运的机理。我们表明，棘轮粒子速度的典型数字可能为50 nm/sec。这是一种相当大的效果，可用于在小于纳米孔宽度的有效过滤颗粒中应用。
We consider the effect of surface undulations of nanochannels on the motion of particles in it. We report the mechanism of surface induced ratcheting transport of particles against fluid flow in nano channels. We show that, the typical number for the velocity of ratcheting particles could be of the order of 50 nm/sec. This is a considerably large effect which could be used for application in efficient filtration of particles smaller than the width of nanopores.
