Abstract
Methods and analyte sensors including a sensor tail comprising at least a first working electrode and a second working electrode that are spaced apart from one another along a length of the sensor tail. A first active area is disposed upon a surface of the first working electrode and a second active area is disposed upon a surface of the second working electrode, the first active area and the second active area being responsive to different analytes. A mass transport limiting membrane is deposited upon the first active area and the second active area by sequential dip coating operations, and the mass transport limiting membrane comprises a bilayer membrane portion overcoating the first active area and a homogeneous membrane portion overcoating the second active area.
