The present disclosure provides an analyte sensor for use in detecting various analytes. In certain embodiments, an analyte-responsive active area of a presently disclosed analyte sensor includes two or more enzyme systems for detecting the analyte. The present disclosure further provides methods for detecting various analytes using the disclosed analyte sensors.

Analyte sensors and methods of use thereof

Analyte sensors are being increasingly employed for monitoring various analytes in vivo. Analyte sensors may feature enhancements to address signals obtained from interferent species. Some analyte sensors may comprise a working electrode comprising an active area disposed thereon and electrode asperities laser planed therefrom. Some analyte sensors may comprise an interferent-reactant species incorporated therewith. Some analyte sensors may comprise an interferent scrubbing electrode. Combinations of these enhancements may additionally be employed.

Analyte sensors featuring enhancements for decreasing interferent signal

Medical devices configured for in vivo assays of one or more analytes can sometimes be problematic if left inserted in a tissue, such as skin, for an extended time. Certain medical device surface profiles may aid in alleviating this issue. Accordingly, medical devices may comprise a base surface having a tissue-facing surface profile defined thereon, and a sensor extending through the base surface and at least a portion of the tissue-facing surface profile. The tissue-facing surface profile deviates from the base surface, and the tissue-facing surface profile is also configured to undergo a change in shape, hardness, or a combination thereof after contacting a tissue for a length of time. A dynamic material may be present in at least a portion of the tissue-facing surface profile.

Medical devices having a dynamic surface profile and methods for production and use thereof

The present disclosure provides analyte sensors including one or more NAD(P)-dependent enzymes and an internal supply of NAD(P) for the detection of an analyte. The present disclosure further provides methods of using such analyte sensors for detecting one or more analytes present in a biological sample of a subject, and methods of manufacturing said analyte sensors.

NAD(P) depot for NAD(P)-dependent enzyme-based sensors

Provided are sensors and sensor applicator sets to insert at least a portion of an analyte sensor into a a skin surface of a subject, as well as methods of using the same.

Analyte sensing devices and methods

NADP-dependent oxidoreductase compositions, and electrodes, sensors and systems that include the same. Analyte sensors include an electrode having a sensing layer disposed thereon, the sensing layer comprising a polymer and an enzyme composition distributed therein. The enzyme composition includes nicotinamide adenine dinucleotide phosphate (NAD(P)) or derivative thereof; an NAD(P)-dependent dehydrogenase; an NAD(P)H oxidoreductase; and an electron transfer agent comprising a transition metal complex.

NAD(P)-dependent responsive enzymes, electrodes and sensors, and methods for making and using the same

A sensor control device and methods of making them are described. The sensor control device includes an electronics housing and a plug assembly. The electronics housing includes an upper shell matable to a lower mount having a skin-facing surface. The plug assembly is coupled to the electronics housing and includes a sensor module that has a sensor and a sharp module having a sharp. The plug assembly includes a base having a skin-facing surface and a plug portion comprising a lumen therethrough. At least a portion of a surface of the electronics housing or the plug assembly comprises an antimicrobial agent. The antimicrobial agent may be a metal and/or a metal oxide.

Antimicrobial and microstatic sensor systems

The present disclosure provides an analyte sensor for use in detecting aspartate and/or asparagine. In certain embodiments, an aspartate-responsive active site of a presently disclosed analyte sensor includes an aspartate oxidase disposed upon a surface of a working electrode. In certain embodiments, an asparagine-responsive active site of a presently disclosed analyte sensor includes an enzyme system comprising an aspartate oxidase and an asparaginase disposed upon a surface of a working electrode. The present disclosure further provides methods for detecting aspartate and/or asparagine using the disclosed analyte sensors.

The present disclosure provides an analyte sensor for use in detecting potassium. In certain embodiments, an analyte sensor of the present disclosure includes at least two asparagine-responsive active areas, where each asparagine-responsive active area includes an asparaginase that exhibits a particular potassium dependency. In certain embodiments, an analyte sensor of the present disclosure includes at least two aspartate-responsive active areas, where each aspartate-responsive active area includes an aspartate oxidase that exhibits a particular potassium dependency. The present disclosure further provides methods for monitoring potassium levels, e.g., in vivo potassium levels, using the disclosed analyte sensors.

Continuous potassium sensors and methods of use thereof

Multiple analytes may be dysregulated singularly or concurrently in certain physiological conditions and may be advantageously assayed together using analyte sensors capable of detecting multiple analytes. Certain analyte sensors capable of the detection of multiple analytes may include first and second working electrodes, analyte-responsive active areas disposed on each of the working electrodes, and reference and counter electrodes. Analyte sensors that include multiple working electrodes but do not include reference and counter electrodes can also be used in conjunction with another sensor that contains reference and counter electrodes, such that these electrodes are shared.
