1. An analyte sensor comprising:
- a working electrode;
a counter electrode; and
a sensing layer disposed on top of the working electrode, wherein the sensing layer comprises a polymer, enzyme, redox mediator and a high-boiling point solvent, and wherein the redox mediator is covalent bonded to the polymer, andwherein the high-boiling point solvent comprises ethylene glycol at a concentration of 1% to 5% (w/v) of the total formulation of the sensing layer.

Abstract
Generally, embodiments of the present disclosure relate to analyte determining methods and devices (e.g., electrochemical analyte monitoring systems) that have improved uniformity of distribution of the sensing layer by inclusion of a high-boiling point solvent, where the sensing layer is disposed proximate to a working electrode of in vivo and/or in vitro analyte sensors, e.g., continuous and/or automatic in vivo monitoring using analyte sensors and/or test strips. Also provided are systems and methods of using the, for example electrochemical, analyte sensors in analyte monitoring.
