Oxford University develops fast-response oxygen sensor

0

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.
