We use a combination of computer simulations and iso-flux tension propagation (IFTP) theory to investigate translocation dynamics of a flexible linear polymer through a nanopore into an environment composed of repulsive active rods in 2D. We demonstrate that the rod activity induces a crowding effect on the polymer, leading to a time-dependent net force that facilitates translocation into the active environment. Incorporating this force into the IFTP theory for pore-driven translocation allows us to characterize translocation dynamics in detail and derive a scaling form for the average translocation time as tau L νr/F SP, where L r and F SP are the rod length and self-propelling force acting on the rods, respectively, and ν is the Flory exponent.
