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.

A method for monitoring a level of an analyte using an analyte monitoring system, the method comprising:
- inserting at least a portion of an analyte sensor into skin of a patient, wherein the analyte sensor comprises a sensing layer disposed thereon and a membrane disposed over the sensing layer, wherein the membrane comprises a low surface tension polymer selected from polydimethylsiloxane (H3C)3Si[Si(CH3)2O]nSi(CH3)3, polyether modified polydimethylsiloxane [CH2O—]n, [Si(CH3)2O]n—[CH2O—]n, poly((eo)(po))butyl terminated polydimethylsiloxane CH3-{[CH2CH2O]n—[CH2O—]n}n [Si(CH3)2O]n{[CH2O—]n[CH2CH2O]n}n—CH3, and dimethyl, methyl (polyethylene oxide acetate-capped) siloxane, wherein n is an integer in a range of from about 1 to 500;
- attaching an analyte sensor control unit to the skin of the patient and the analyte sensor;
- collecting data, using the analyte sensor control unit, regarding a level of an analyte from signals generated by the analyte sensor;
- transmitting the collected data from the sensor control unit to a receiver unit.
