Particle manipulation

Abstract

The present invention relates to the manipulation and, more particularly, to the sorting of particles. Still more particularly, the present invention relates to the use of acoustic waves, including surface acoustic waves, for the manipulation and sorting of particles. In an example, the present invention may be used for the sorting of cells. In an aspect of the invention, there is provided a device for manipulating a particle in a fluid suspension, the device comprising: (a) a substrate having a surface; (b) an acoustic source configured to generate and deliver an acoustic wave within a region of the substrate surface; and (c) a pillar disposed on the surface of the substrate and the pillar is configured to receive a channel, the channel configured to receive the fluid suspension, wherein the acoustic wave delivered within the region of the substrate surface is delivered to the fluid suspension in the channel through the pillar. A method using the device of the invention is also disclosed.
