Active control of transport through nanopores

Passive particle transport through narrow channels is well studied, while for active systems, it not understood. Here, we demonstrate the control of a nanopore via mean-field analysis and molecular dynamics simulations. We prove that force enhances efficiency with an effective diffusion coefficient $D_{eff} = D_t (1 + Pe^2/6)$, where $D_t$ translational coefficient, $Pe$ P\'{e}clet number determines strength force. For particles inside channel, experiences subdiffusion at short times then turns to normal longer times. Finally, extend our research several sinusoidal shapes channel surface. More are trapped in if roughness surface increased, resulting fewer transported from one side other.
