Abstract
The steady state concentration and current occurring at a microdisk enzyme electrode when a product from an immobilized enzyme reacts with the electrode is derived. A closed form of an analytical expression of concentration for the full range of enzyme activities has been derived. A simple approximate analytical expression of current in terms of all dimensionless parameters for film thickness r1/r0r1/r0 and enzyme kinetic χr0χr0 for all values of Michaelis-Menten constant is also reported. Available limiting case results are compared with our results and are found to be in good agreement.
