1. A method of transporting material, comprising:

  • providing a first channel segment, a second channel segment, and a third channel segment, each channel segment having first and second ends, wherein the second end of the first channel segment, the first end of the second channel segment, and the first end of the third channel segment are fluidly coupled at a first fluid junction;

    applying a pressure differential between the first end of the first channel segment and the second end of the third channel segment to produce a first flow profile in the first channel segment, the first flow profile being dominated by non-electrokinetically driven pressure flow; and

    applying a voltage differential between the second end of the second channel segment and the second end of the third channel segment to produce a second flow profile in the second channel segment, the second flow profile being dominated by electrokinetic flow;

    thereby transporting material through the first channel segment and into the second channel segment.
