In this paper we present the standing wave created from two counter-propagating non-diffracting (Bessel) beams as a device for confinement and precise delivery of sub-micron sized particles. The particle position in direction of beam propagation is controled by changing the phase shift between these two beams. We succeeded in delivery of polystyrene particles of diameter 410 nm over a distance of 300 μm. At the same time we experimentaly confirmed the theoretical prediction how the optical forces acting on particles in this kind of field depend on the size of the objects.
