摘　　要：Here,we developed a novel electrochemiluminescence resonance energy transfer(ECL-RET) approach between Ru(bpy)_3^(2+) and Au nanorods(NRs) for sensitive determination of H_2O_2.Au NRs were synthesized through silver ion-assisted seed-mediated method which exhibited an obvious absorption peak at about 627 nm.They were modified at glassy carbon electrode(GCE) surface which showed a significant ECL quenching efficiency about 56.5%due to the ECL-RET process.This Au NRs modified electrode was then utilized to measure the concentration of H_2O_2 on the basis of the significant quenching effect of H_2O_2 on Ru(bpy)_3^(2+) ECL.Results demonstrated that the decrement of ECL intensity at Au NRs modified electrode had ~ 6.6-fold enhancement as compared with that at bare electrode.Here,we developed a novel electrochemiluminescence resonance energy transfer（ECL-RET） approach between Ru（bpy）3^2＋ and Au nanorods（NRs） for sensitive determination of H2O2.Au NRs were synthesized through silver ion-assisted seed-mediated method which exhibited an obvious absorption peak at about 627 nm.They were modified at glassy carbon electrode（GCE） surface which showed a significant ECL quenching efficiency about 56.5%due to the ECL-RET process.This Au NRs modified electrode was then utilized to measure the concentration of H2O2 on the basis of the significant quenching effect of H2O2 on Ru（bpy）3^2＋ ECL.Results demonstrated that the decrement of ECL intensity at Au NRs modified electrode had - 6.6-fold enhancement as compared with that at bare electrode.
