Abstract
The relative specificity of the enzyme galactose oxidase for various substrates is controlled as a function of the electrical potential applied to the enzyme. The enzyme is incorporated into a thin layer electrochemical cell laminate having exterior membrane layers and an interior enzyme layer. An electrode located within the enzyme layer applies varying electrical potentials to the enzyme. An intermediate electron transfer agent may be used to transfer electrons to and from the enzyme and electrode.
