  • Publication number: 20240074682
    Abstract: Devices and methods for measuring a concentration of a target analyte in a biological fluid in vivo are provided herein. In some examples, a device includes an indwelling sensor and sensor electronics. The sensor may include a substrate; a first electrode disposed on the substrate; an ionophore disposed on the substrate to selectively transport the target ion to or within the first electrode; and a second electrode disposed on the substrate. The sensor electronics is configured to generate a signal corresponding to an electromotive force which is at least partially based on a potential difference that is generated between the first electrode and the second electrode responsive to the ionophore transporting the target ion to the first electrode.

  • Publication number: 20230138407
    Abstract: Disclosed are devices for determining an analyte concentration (e.g., glucose). The devices comprise a sensor configured to generate a signal associated with a concentration of an analyte and a sensing membrane located over the sensor. The sensing membrane comprises an enzyme layer, wherein the enzyme layer comprises an enzyme and a polymer comprising polyurethane and/or polyurea segments and one or more zwitterionic repeating units. The enzyme layer protects the enzyme and prevents it from leaching from the sensing membrane into a host or deactivating.
