Fig. 2. Experimentally observed shifts of the oxidative stripping peak potentials E P with decreasing metallic NP radii. Linear sweep voltammograms (LSVs) were obtained in 10 mM potassium bromide plus 0.1 M HClO4 electrolyte at 1 mV s–1 on glass/ITO electrodes coated with electrochemically or chemically synthesized Au NPs of varying radii.
