  • Publication number: 20180192932
    Abstract: Analyte sensor assemblies comprising: an electrochemical sensor for determining a concentration of an analyte and an electrochemical sensor control unit. The electrochemical sensor comprising a working electrode having a sensing layer and a non-crosslinked cubic phase lyotropic liquid crystal membrane disposed over the sensing layer, the sensing layer comprising an analyte-responsive enzyme, and a counter electrode in communication with the working electrode. And the electrochemical sensor control unit comprising a housing adapted for placement on or implantation in a patient's skin, and sensor control unit electronics. Wherein a measured current from an applied potential between the working electrode and the counter electrode correlates to a concentration of an analyte.

  • Patent number: 9907500
    Abstract: The present invention is directed to membranes composed liquid crystals having continuous aqueous channels, such as a lyotropic liquid crystal, including a cubic phase lyotropic liquid crystal, and to electrochemical sensors equipped with such membranes. The membranes are useful in limiting the diffusion of an analyte to a working electrode in an electrochemical sensor so that the sensor does not saturate and/or remains linearly responsive over a large range of analyte concentrations. Electrochemical sensors equipped with membranes of the present invention demonstrate considerable sensitivity and stability, and a large signal-to-noise ratio, in a variety of conditions.
