Sensor for detecting the amount of analyte in a sample

摘要

A sensor (1) or detecting and/or quantifying the amount of analyte in a sample, the sensor including: • -a sensing region (3); and • -a barrier layer (BL) including a reactive oxygen species (ROS) -quenching, analyte-permeable membrane having an ROS- quenching agent adsorbed thereto; • wherein the sensor is adapted so that the sample enters the sensing region of the sensor through said barrier layer.
