Abstract:
A method of assembling members of a group consisting of any of inorganic and bio-organic substances and molecules, and beads, pucks and other small things that are capable of holding an electrical charge, the method comprising:photolithographically first-patterning a photosensitive electrode so that the electrode assumes first regions that are charged to a first electrical polarity and second regions that are charged to a second, opposite, electrical polarity; and second-patterning members selected from the group consisting of any of inorganic and bio-organic substances and molecules, and beads, pucks and other small things that are both (i) electrically charged to a first polarity, and (ii) immersed in a fluid transport medium that is upon the electrode, by moving under force of an electric field these members to charged second regions of the first-patterned electrode which second regions are of an opposite electrical polarity to the members; wherein the members respond to the electric field and accumulate on, and assume the pattern of, the second regions.
