Abstract
The aim of this work was to develop needle based sensors for oxygen sensing using different types of membranes. For oxygen sensors it is important to achieve fast response time, good linearity, low biofouling and high sensitivity. The effect of different types of polymeric barrier membranes and their various combinations were assessed and compared. An optimized system was thereby selected: sensors covered with polyurethane membrane doped with surfactant showed good stability with a linear working range up to 750 mmHg pO2.
