Abstract

Here, we developed a novel electrochemiluminescence resonance energy transfer (ECL-RET) approach between Ru(bpy) and Au nanorods (NRs) for sensitive determination of HO. 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 HO on the basis of the significant quenching effect of HO on Ru(bpy) 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. [ABSTRACT FROM AUTHOR]
