Title: The development and characterisation of square microfabricated electrode systems
Abstract: This paper outlines the systematic production and characterisation of biocompatible square microfabricated electrode systems for electroanalysis. In contrast to previous results, a combination of simulation, theoretical analysis and measurement has established that there is an enhanced current density for a microsquare electrode under mass transport limiting current conditions when compared to a microdisc of equivalent size. This is not simply due to a difference in the effective areas of the electrodes as the difference is frequency (diffusion layer thickness) dependent; it can instead be attributed to the effects of enhanced diffusion at the corners of the microsquares on the growing diffusion layer.
