Abstract

We demonstrate how the standing wave created from two counter-propagating non-diffracting (Bessel) beams can be used for confinement of sub-micron sized particles. At the same time we proved that changing the phase shift between these two beams can be efficiently used for precise delivery of sub-micron objects in unison. We succeeded in delivery of polystyrene particles of diameter 410 nm over a distance of 300 μm.
