Abstract
Generally, embodiments of the invention relate to analyte determining methods and devices (e.g., electrochemical analyte monitoring systems) that have improved uniformity of distribution of one or more components of the sensor by inclusion of a low surface tension polymer leveling agent, where the components are 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.
