Fig. 4. Motion trajectories (red line) of individual NPs and time-resolved current traces (black line) during electrochemical oxidation with AgNPs approaching the electrode surface simulated well using a dynamic Monte Carlo simulation. Current–time (left black ordinate) and distance–time (right red ordinate) of AgNPs with sizes of 10 nm (a), 20 nm (b), 40 nm (c), 60 nm (d), and 80 nm (e). The initial positions of the AgNPs are arbitrary.
