Claim 12:
13. A method for forming a cyclic capillary electrophoresis device according to claim 1, comprising:
forming the capillary channel in the substrate, the capillary channel forming the loop that is closed;
forming in the substrate a first charge-inducing structure configured to be turned on to induce charges on at least part of the inner wall surface of the inner half;
forming in the substrate a second charge-inducing structure configured to be turned on to induce charges on at least part of the inner wall surface of the outer half;
modifying a material composition of the inner wall surface of the inner half and of the inner wall surface of the outer half, wherein the modification creates the charge density difference between the inner wall surface of the inner half and the inner wall surface of the outer half; and
bonding a cover to the substrate to thereby close the capillary channel.
