1. An apparatus for particle focusing of particles within a fluid sample, the apparatus comprising:

  • a substrate, having a substrate surface;

    a surface acoustic wave generator, operable to generate a surface acoustic wave (SAW) within a SAW region of the substrate surface; and

    a channel, configured to receive the fluid sample,the channel having a particle focusing portion proximate the SAW region of the substrate,the particle focusing portion providing focused particles within the fluid sample when the SAW is generated.
