A different paradigm is proposed to selectively manipulate and transportsmall engineered chiral particles and discriminate different enantiomers usingunstructured chiral light. It is theoretically shown that the response of achiral metamaterial particle may be tailored to enable an optical conveyor beltoperation with no optical traps, such that for a fixed incident light helicitythe nanoparticle is either steadily pushed towards the direction of the photonflow or steadily pulled against the photon flow, independent of its position.Our findings create distinct opportunities for unconventional opticalmanipulations of tailored nanoparticles and may have applications in sortingracemic mixtures of artificial chiral molecules and in particle delivery.
