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