✦ Synopsis

Glucose sensors are constructed by immobilizing glucose dehydrogenase physically or chemically on a carbon or platinum electrode. Soluble coenzyme was used. The usefulness of the electrode is limited by interference from any molecule that can be oxidized at + 450 mV. Because the cofactor must be in solution, and diffuse to the electrode, a low-molecular-weight cut-off filter cannot be used to block the interferences.
