Abstract
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.
