Abstract

A motional array of optical traps created by interference of two counter-propagating waves can be used for particle delivery. The mean particle speed is affected by jumps between neighboring traps and is always lower than the velocity of the trap array. We show that a significant enhancement of the delivery speed can be obtained if several particles are delivered simultaneously. We speculate that optical binding between particles and hydrodynamical drafting cause this speed enhancement.
