Abstract
Devices are presented for measurement of an analyte concentration. The devices comprise: a sensor configured to generate a signal indicative of a concentration of an analyte; and a sensing membrane located over the sensor. The sensing membrane comprises an enzyme domain comprising an enzyme, a base polymer, and a hydrophilic polymer which makes up from about 5 wt. % to about 30 wt. % of the enzyme domain.
