Abstract

The motion of rigid particles and long flexible molecules was investigated through a nanochannel. A wall was found to be the cause of liquid molecules ordering themselves parallel to the surface in the region within a dozen molecular diameters perpendicular to the wall. It was shown that for a size ratios as small as 3/1 the continuum mechanical expression for drag force worked accurately. It was found that the motion of a suspended nanometer size particles in nano-devices is strongly influenced by the presence of surface forces and by the random molecular motion of the suspending fluid.
