Abstract

La présente invention concerne un senseur colorimétrique d'oxygène dont le principe de fonctionnement est une réaction d'oxydation enzymatique. C'est un solide hydrogel sur lequel nous avons immobilisé la ppo et son substrat en absence d'oxygène. Le contact du senseur avec l'oxygène engendre l'oxydation du substrat, selon une réaction irréversible, en produisant des substancescolorées comme illustré sur la figure -2-The present invention relates to a colorimetric oxygen sensor whose operating principle is an enzymatic oxidation reaction. It is a solid hydrogel on which we immobilized the ppo and its substrate in the absence of oxygen. The contact of the sensor with the oxygen causes the oxidation of the substrate, in an irreversible reaction, producing substances colored as illustrated in FIG.
