Chemical modification of analyte permeable membrane for enhanced oxidative stability

Abstract

A sensor that may be used to detect the presence, amount, and/or concentration of an analyte in a medium within an animal. The sensor may include a sensor housing, an indicator element embedded within and/or covering at least a portion of the sensor housing, and a membrane over the indicator element. The sensor may include one or more of a first coating on an inner surface of the membrane, a second coating on an outer surface of the membrane, and a layer on the outside of the indicator element. One or more of the first coating, second coating, and layer may reduce deterioration of the indicator element by catalyzing degradation of reactive oxygen species (ROS). The one or more coatings on the membrane may increase the light blocking capability of the membrane, which may improve the accuracy of the sensor.
