Claim Text:
1. A method, comprising: disposing a plurality of particles selectively within a set of wells on a first surface, wherein the set of wells is one of a plurality of sets of wells, and wherein each set of wells is spaced at intervals along a longitudinal axis of the first surface by a spacing distance from an adjacent set of wells; generating, via a transducer, an acoustic wave with an amplitude corresponding to the spacing distance, such that the first surface and the set of wells is displaced from a static position by at least one half the spacing distance along the longitudinal axis at a peak amplitude of the acoustic wave; transferring the particles of the set of wells from the first surface to a buffer surface when the first surface is displaced by a first displacement distance by the acoustic wave relative to the static position; and returning the transferred particles from the buffer surface to the first surface when the first surface is displaced a second displacement distance by the acoustic wave relative to the static position, wherein the first displacement distance is different from the second displacement distance, such that each of the plurality of particles is shifted from an original well to a different well.
