ABSTRACT:
Electrophoretic chambers having at least a region of surface modification, and methods for their fabrication, are provided. In some embodiments the subject chambers include in the region of surface modification an anchoring polymeric layer interpenetrating the surface of the chamber and an electrophoretic polymeric layer copolymerized with the anchoring polymeric layer. The subject chambers are prepared by sequentially contacting the chamber surface with a first monomer capable of interpenetrating the surface and a second monomer capable of copolymerization with the first monomer, followed by copolymerization of the first and second monomers. In other embodiments an electrophoretic polymeric layer is noncovalently bound on the surface of a rigid polymereic base material without the aid of a separate anchoring polymeric layer. The subject devices find use in any of a variety of electrophoretic applications in which entities are moved through a medium under the influence of an applied electric field.
