  • 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: 20220098636
    Abstract: Detection reagents, multi-analyte test elements, test systems, and multi-analyte measuring methods are provided. In particular, multi-analyte test elements have (1) a first working electrode and first counter electrode pair covered with a first analyte-specific reagent that includes an enzyme, a coenzyme and a first mediator and have (2) a second working electrode covered with a second analyte-specific reagent that includes an enzyme, a coenzyme and a second mediator, where the second mediator is different than the first mediator. The single counter electrode can be used as the counter electrode for both the first and second analyte measurements at their respective working electrodes. Moreover, the mediator concentrations, measurement ranges, and applied potential differences are not the same for each analyte-specific measurement.

  • Patent number: 10508267
    Abstract: The present disclosure relates to a mutant 3-hydroxybutyrate dehydrogenase (3-HBDH) with improved performance relative to the wild-type 3-HBDH, a nucleic acid encoding the mutant 3-HBDH, a cell having the mutant 3-HBDH or the nucleic acid, and/or a method of determining the amount or concentration of 3-hydroxybutyrate in a sample. Also disclosed is the use of the mutant 3-HBDH for determining the amount or concentration of 3-hydroxybutyrate in a sample, and a device for determining the amount or concentration of 3-hydroxybutyrate in a sample.
