Abstract:
An analyte sensor for measuring physiological parameters, a method for making the analyte sensor, and method of measuring a level of an analyte in a subject are disclosed. In one aspect, the analyte sensor includes a crosslinked, hydrophilic copolymer in contact with a surface of an electrode, and an analyte sensing component embedded within the crosslinked, hydrophilic copolymer. The crosslinked, hydrophilic copolymer has methacrylate-derived backbone chains of first methacrylate-derived units, second methacrylate-derived units and third methacrylate-derived units. The first and second methacrylate-derived units have side chains that can be the same or different, and the third methacrylate-derived units in different backbone chains are connected by hydrophilic crosslinks. The crosslinked, hydrophilic copolymer has an analyte permeability that is substantially temperature independent. The analyte sensor generates signals that are substantially temperature independent over a range of temperatures.
