Abstract
A device for delivery of an insulin or insulin analog formulation and measurement of subcutaneous glucose concentration may comprise a hollow tube, and an amperometric glucose sensor located proximal to a distal end of the hollow tube. The amperometric glucose sensor may comprise a redox mediator and an enzyme comprising glucose oxidase or glucose dehydrogenase. An applied bias potential may allow an electrode layer of the amperometric glucose sensor to undergo substantially no electropolymerization of an excipient of the insulin or insulin analog formulation during continuous operation of amperometric glucose sensor. A sensitivity of the amperometric glucose sensor to the subcutaneous glucose concentration may be maintained in presence of the insulin or insulin analog formulation.
