1. A method of fabricating a device for measuring a concentration of an analyte, the method comprising the steps of:

  • providing a sensor configured to measure the analyte or a product of a reaction representative of the analyte;

    forming a composition comprising a blend of a first polymer and a second polymer, wherein the first polymer is at least partially hydrophilic and the second polymer is at least partially hydrophobic;

    maintaining the composition at a temperature sufficient to maintain solubility of the first polymer and the second polymer;

    forming a film from the composition at the temperature;

    drying the film to form a membrane; and

    coupling the membrane to the sensor.
