1. A method of enhancing material transport by electroosmotic flow of a fluid containing said material, comprising:

  • providing at least first and second discrete fluid volumes in a fluid filled channel, a first material being contained in said first discrete fluid volume, but not in said second discrete fluid volume; and

    providing an effective concentration of at least one zwitterionic compound in said first discrete volume of fluid containing said first material to reduce an electrophoretic mobility of said first material relative to an electroosmotic flow of said first discrete fluid volume containing said material.
