Possibility for an Immobilized Flavin Fuel Cell Electrode for Glucose Measurements

Preliminary work is described on the attachment of riboflavin to solid carbon via a coupling group that should provide a pathway for easy electron transfer. Such an approach, when extended to the flavin cofactor portion of glucose oxidase, has the possibility of forming a fuel cell electrode of high specificity for glucose and in which the current would be related to the concentration of glucose.
