Claims19
An analyte sensor comprising:
- (i) an in vivo portion comprising at least a first working electrode;
- (ii) a first active area disposed upon a surface of the first working electrode, wherein the first active area comprises one or more enzymes responsive to a first analyte;
- (iii) a first mass transport limiting membrane permeable to the first analyte that overcoats at least the first active area,
- wherein the first mass transport limiting membrane comprises a copolymer of at least a first monomer comprising an acrylamide and a second monomer comprising a heterocycle-containing component, wherein the acrylamide is an N-alkyl acrylamide and the heterocycle comprises pyridine.
