Characterization of Glucose Oxidase-Modified Poly(phenylenediamine)-Coated Electrodes in vitro and in vivo: Homogeneous Interference by Ascorbic Acid in Hydrogen Peroxide Detection
TL;DR: The response of glucose oxidase (GOx) modified poly(o-phenylenediamine) coated Pt disk electrodes to glucose was well-behaved with a rapid response time and displaying Michaelis-Menten kinetics but the glucose response was lowered in a concentration-dependent manner by ascorbic acid when the glucose calibrations were carried out in solutions containing this reducing agent.

Strategies for decreasing ascorbate interference at glucose oxidase-modified poly(o-phenylenediamine)-coated electrodes
Karl McAteer,Robert D. O'Neill +1 more
TL;DR: The current ratio IGluc/IAA for 1 mmol l–1 glucose and 500 µmol l-1 AA for the best 50% of the lipid-modified Pt/PPD/GOx electrodes was approximately 30:1, indicating that these sensors are well suited for monitoring brain glucose in vivo.

Efficient glucose detection in anaerobic solutions using an enzyme-modified electrode designed to detect H2O2: implications for biomedical applications
TL;DR: The finding that a ‘first generation’ glucose oxidase modified poly(o-phenylenediamine) coated Pt electrode, designed to detect H2O2, responded to glucose in N2-s saturated solutions with a sensitivity similar to that of air-saturated media is of cosiderable significance for the application of biosensors in biological systems where O2 availability is severely restricted.
