Typical CVs of (a) bare GC, (b) Pt/GC, (c) GR/GC, and (e) Pt/GR/GC electrode in 0.1 M pH 5.0 phosphate buffer solution containing 5 𝜇M rutin. (d) CV of Pt/GR/GC electrode in 0.1 M pH 5.0 phosphate buffer solution without Rutin. Inset: comparison of anodic peak currents obtained in 5 𝜇M rutin solution at different electrodes.
