| contents | We study the translocation of a flexible polymer through extended
patterned pores using molecular dynamics (MD) simulations. We
consider cylindrical and conical pore geometries that can be
controlled by the angle of the pore apex $α$. We obtained the
average translocation time $\langle τ\rangle$ for various chain
lengths $N$ and the length of the pores $L_p$ for various values
$α$ and found that $\langle τ\rangle$ scales as $\langle
τ\rangle \sim N^γ\mathcal{F}\left( L_p N^ϕ\right)$
with exponents $γ= 3.00\pm0.05$ and $ϕ= 1.50\pm0.05$ for
both patterned and unpatterned pores. |
