Abstract: 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 having sensing portion and an exposed electrode portion, wherein the sensing portion comprises an active area having an analyte-responsive enzyme disposed thereupon and the exposed electrode portion comprises no active area. The exposed electrode portion and the sensing portion may be present in a ratio of and about 1:10 to about 10:1.
