The sensing method features an immobilised pT based luminophore that is excited by the light of a blue LED and emits a red light. Dissolved oxygen quenches this excitation.\u003c\/p\u003e \u003cp\u003eThe major components of the probe include a blue LED for excitation, a red LED that is used as a reference light, and a photodetector.
