From: Role of reaction kinetics and mass transport in glucose sensing with nanopillar array electrodes

A 2D model of a circular electrochemical cell containing a functionalized nanopillar electrode. The inner center circle is for generating the swirling vortex force to stir the solution and the small off-center circle is for creating a drop of uniform concentration of glucose prior to the kinetics analysis. A magnified view of the nanopillar electrode is shown at the upper right corner.
