1. A microfluidic device for mixing a plurality of fluid streams, the mixing device comprising:

  • a plurality of microfluidic inlet channels that merge into a microfluidic junction channel, the junction channel being defined in a first device layer and having a characteristic cross-sectional area; and

    a plurality of contraction/expansion regions in fluid communication with the junction channel and arranged in series, each contraction/expansion region including;

    an aperture defined in a second device layer, the aperture having a characteristic cross-sectional area that is substantially smaller than the area of the junction channel; and

    a microfluidic expansion channel defined in either the first device layer or a third device layer, the expansion channel having a characteristic cross-sectional area that is substantially larger than the area of the aperture.
