1. An apparatus, the apparatus being a microfluidic device comprising:

  • a substrate, the substrate being generally planar;

    a sample flow inlet, configured to receive a sample flow;

    a first flow inlet, configured to receive a first sheath flow; and

    a curved channel, the curved channel configured to receive the sample flow and the first sheath flow,the sample flow inlet, the first flow inlet, and the curved channel being supported by the substrate, the curved channel being generally parallel to the substrate,the curved channel being configured to provide out-of-plane hydrodynamic focusing of the sample flow,the sample flow being compressed along a direction normal to the substrate.
