Researchers at the University of Oxford have produced a fast-response composite matrix that allows for the detection of oxygen in liquids and gases.
The matrix can be used in the construction of optical sensors for oxygen measurements in medical, biomedical or industrial applications, in a faster, more robust manner than current sensors.
Optical oxygen sensors depend on measuring the light emitted by a luminescent dye when interacts with oxygen. The oxygen sensing matrix developed by the university is a composite of a biocompatible acrylate polymer, carbon nanomaterial and a commercial metalorganic dye. The incorporation of carbon nanomaterials produces a very fast time response (less than 100 ms), even when the thickness of the sensing matrix is increased to improve its robustness. The biocompatibility of the polymer broadens the use of this matrix into medical applications.
Oxford University Innovation has filed a patent application on this technology and would like to speak to potential partners interested in developing it for biomedical, or industrial applications.
Sensor Electronics, a gas detection equipment specialist based in Minnesota, has installed uninterrupted oxygen (O2) sensors for Saint Paul-based gas distribution corporation, Oxygen Service Company, which the business states are “working backwards.”
Oxygen sensors at a Saint Paul, MN-based gas distribution company are working backwards. Instead of looking for oxygen concentrations in the company laboratories, they are looking for no oxygen. For Oxygen Service Company, monitoring gas levels in the labs helps assure employee safety. To keep a beady eye on those ...
