1. A microfluidic structure comprising:

  • a first surface including a pneumatic channel;

    a second surface including a fluidic channel; and

    an elastomer membrane located between the first and second surfaces such that the application of a pressure or a vacuum to the pneumatic channel causes the membrane to deflect to modulate a flow of a fluid in the fluidic channel.
