Transport of passive particles induced by chiral-active particles in microchannel is investigated by using the overdamped Langevin dynamics simulation in a two-dimensional model system.Due to the chirality of active particles and special structure of microchannel,effective ratchet transport of passive particles is achieved.Effective transport of passive particles depends on the width of microchannel (d),the density (p),and the angular velocity (ωo) of chiral-active particles.There exist optimal parameters for d and ω at which the transport efficiency for passive particles takes its maximal value.This investigation can help us understand the necessity of active motion for living systems to maintain a number of vital processes such as materials transport inside cells and the foraging dynamics of mobile organisms.
