An electrospun poly(acrylonitrile-co-actylic acid) nanofiber mat (PAN-co-PAAnfm) was successfully collected on the surface of a glassy carbon electrode (GCE). Scanning electron microscope (SEM) images showed that the porous electrospun mat was composed of -160 nm diameter of uniform knitted nanofibers. The cationic luminescence probe, tris(2,2'-bipyridyl)ruthenium(Ii) complex ([Ru(bpy)3]2+), was innovatively and first incorporated into the negatively charged PAN-coPAA,-modified GCE via electrostatic interaction. Compared with the [Ru(bpy)3]2+ immobilized on normal PAN-co-PAA deposited coating, [Ru(bpy)3]2+/ PAN-co-PAAnfm exhibited dramatically enhanced electrochemical and electrochemiluminescence (ECL) performances, namely, more than 100 times higher ECL intensity could be feasibly obtained via the elecfrospinning technique.
