1. A method for monitoring a level of an analyte, the method comprising:
- inserting an electrochemical sensor into skin of a patient, wherein the electrochemical sensor comprises;
a working electrode comprising a sensing layer disposed thereon;
a membrane disposed over the sensing layer, wherein the membrane comprises a hydrogel, a crosslinker, and a swelling modulator comprising a 3-arm epoxide;
collecting data regarding a level of an analyte from signals generated by the sensor;
transmitting the collected data to a display unit; and
displaying an indication of the level of the analyte on a display of the display unit.

Abstract
Generally, embodiments of the present disclosure relate to analyte determining methods and devices (e.g., electrochemical analyte monitoring systems) that have improved signal response and stability by inclusion of a coating including a hydrogel, a crosslinker, and a swelling modulator, where the coating 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.
