Concurrent Potentiometric and Amperometric Sensing With Shared Reference Electrodes

Adomian Decomposition Approach to a Mathematical Modeling and Analysis of Potentiometric and Amperometric Enzyme Electrodes

A mathematical model to describe the concentration of profiles and flux for potentiometric and amperometric enzyme electrodes and of enzyme reactors has been developed. This model contains a non-linear term related to Micahlies-Menten kinetics. Analytical expressions pertaining to the substrate concentration and product concentration were reported for all values of parameters P S   , and  . ...

Microneedle electrodes toward an amperometric glucose-sensing smart patch.

Here, efforts toward the development of a microneedle-based glucose sensor or "smart patch" for intradermal glucose sensing are described. Metallic microneedle array electrodes, conducting polymers, and glucose oxidase form the sensor platform. This work represents the first steps toward the development of painless, transdermal-sensing devices for continuous glucose monitoring.

Amperometric Oxygen Electrodes

Although the Winkler method is very precise when performed with strict control of pH and iodine concentration, it is still susceptible to errors. For example, ions such as Fe2+ and SO3-, suspended solids, and some organics can produce gross inaccuracies. There have been numerous modifications of the method over the years to compensate for its shortcomings (2). Besides the errors inherent in the...
