Monitoring the activity of glucose oxidase during the cultivation of Aspergillus niger using novel amperometric sensor with 1, 1′-dimethylferricinium as a mediator

1, 1′-dimethylferricinium (DMF +), a deep blue, and stable mediator, was prepared from a water-soluble 1, 1′-dimethylferrocene(DMF):2-hydroxypropyl-β-cyclodextrin complex via enzymatic oxidation using immobilised bilirubin oxidase. This mediator was superior to other soluble ferrocenes, notably carb...
