Abstract

The present invention discloses an electrophoretic chip comprising: (a) a non-conductive substrate designed to support elements of said electrophoretic chip; (b) an electrode structure for conducting current through said electrophoretic chip, printed on said non-conductive substrate and comprising a counter electrode and at least one working electrode, each electrode comprising a conductive low-resistance ink layer printed on the non-conductive substrate, and a carbon ink layer printed on top of and fully or partially covering said conductive low-resistance ink layer; (c) a dielectric ink insulator layer placed on top of, and covering, said electrode structure, said dielectric ink insulator layer having at least one opening above the counter electrode and at least one opening above said at least one working electrode, thereby forming at least one addressable location; and (d) a molecule capturing matrix spotted on and covering said at least one addressable location, thereby creating at least one microgel region.
