Figure Lengend Snippet: Concentration profiles of the analyte (mol L −1 ) in a simplified electrochemical reaction in a microfluidic channel calculated using COMSOL. ( A ) using a microband electrode (side view) and ( B ) using 16 vertical posts as electrodes (top view). The channel dimensions, flow rates ( V f ) and over-potential are the same in both systems. Red color denotes high concentration and blue color low concentration. In (A) the collection efficiency is a mere 3% compared to 81.5% in (B).
