A single layer membrane comprising a siloxane monomer and which is permselective for oxygen is described. The siloxane monomer is polymerized directly onto a non-porous support material by glow discharge polymerization to form a membrane thereon. The resulting membrane has an oxygen content of between about 10 % and 60 % and is highly permselective for oxygen. The membrane can be deposited upon electrochemical or optical sensors, thereby forming an oxygen sensing device that is resistant to fouling, contamination and interferences. Such a membrane deposited upon a sensor exhibits high conformity and adhesion to the sensor, as well as excellent uniformity, freedom from defects, and durability. An electrochemical sensing device comprising a working electrode, a counter electrode, and a reference or auxiliary electrode, which are contiguous with the permselective membrane, is also described. |
