  • Particle focusing within a microfluidic device using surface acoustic waves
    Patent number: 8573060
    Abstract: Examples of the present invention include apparatus and methods for particle focusing, for particles within a fluid sample. An example apparatus, which may be a microfluidic device, comprises a substrate, a channel receiving the fluid sample, and at least one surface acoustic wave (SAW) generator. The SAW generator may comprise electrodes supported by the substrate. In some examples, the channel has a particle focusing region located near a region of the substrate surface in which a SAW is generated. Particles are concentrated within one or more particle focus regions of the sample flow (the particle focus regions being appreciably narrower than the channel dimensions) by the effects of the SAW. As an example, a pair of SAW generators can be used to generate a standing surface acoustic wave (SSAW) that is used for particle focusing.
