Superconducting colloids producedby exfoliation of Bi-based compounds with high superconducting transition temperatures (high-T(c)s) can be used as precursors to synthesize superconducting films and nanowires by a simple electrophoretic-deposition technique. Organic-salt intercalates of Bi2Sr2CaCu2O8, exfoliated by ultrasonication in acetone, can easily be used to coat silver microfibers (see Figure). These results may be significant for high-T-c superconducting film/wire fabrication.
