Room temperature flashing Ratcheting in nano-channels

We consider surface-induced ratcheting transport of particles in nano-channels, particularly at room temperature. show that temperature it is possible to achieve about 10 nm size a nano-channel 100 width. The typical velocity such case could be the order few hundred nano-meter when surface undulations are wavelength and amplitude tens nano-meter. At temperature, viscosity fluid enabling nano-channels comes out water. here considerably large effect under realistic conditions which used for application efficient filtration probably use biological systems typically work
