1. A method for moving charged particles through a medium, comprising:

  • placing the charged particles in a movement area having defined boundaries, formed on a non-porous, non-electrically conductive substrate with neglible surface charge, and containing multiple electrodes at each end and within each movement area, the electrodes separated by a distance between one and 100 microns, the electrodes providing a plurality of electrical fields to the movement area, and a medium therein, wherein the medium is comprised of particles different from the charged particles and provides frictional resistance to the charged molecules moving through the medium;

    generating a moving electrical field along a given direction of the medium by sequentially activating electrodes placed along the movement area in a time-controlled fashion; and

    continuing to generate the fields in order to cause the charged particles to move in response to the field through the medium.
