Abstract
Analyte sensors responsive at low working electrode potentials may comprise an active area upon a surface of a working electrode, wherein the active area comprises a polymer, a redox mediator covalently bonded to the polymer, and at least one analyte-responsive enzyme covalently bonded to the polymer. A specific redox mediator responsive at low potential may have a structure of wherein G is a linking group covalently bonding the redox mediator to the polymer. A mass transport limiting membrane permeable to the analyte may overcoat the active area. In some sensor configurations, the mass transport limiting membrane may comprise a membrane polymer crosslinked with a branched crosslinker comprising three or more crosslinkable groups, such as polyethylene glycol tetraglycidyl ether.
