Regulation of the catalytic activity of enzymes immobilized on carbon nanotube electrodes was achieved by changing their local pH environment using electrochemical reactions. Reduction of oxygen increased the interfacial pH while oxidation of ascorbate decreased it, thus allowing changing rates of enzymatic reactions of electrode-immobilized amyloglucosidase and trypsin enzymes over a wide activity range.

Abstract
Regulation of the catalytic activity of enzymes immobilized on carbon nanotube electrodes was achieved by changing their local pH environment using electrochemical reactions. Reduction of oxygen increased the interfacial pH while oxidation of ascorbate decreased it, thus allowing changing rates of enzymatic reactions of electrode-immobilized amyloglucosidase and trypsin enzymes over a wide activity range.File in questo prodotto:
