Sensors in contact with biological environments still suffer a lack of stability due to biological attacks. A functional sensor interface that does not influence the analyte path to the sensor nor the measured signal but protects the sensor from these attacks may be realized by using hydrogels. To minimize this influence and to optimize other interesting properties of these water- containing polymers within a sensor device, a test environment is presented and first results are shown.
