Notes:
Summary Enzyme electrodes were assembled by coimmobilizing peroxidase and lactate oxidase or glucose oxidase and additionally glucoamylase for maltose measurement to a fluoride ion sensitive electrode. These sensors for glucose, maltose and lactate, respectively, are based on the peroxidase-catalyzed reaction of 4-fluoroaniline with hydrogen peroxide produced in the reaction of glucose oxidase or lactate oxidase. The concentration of fluoride ions resulting from the peroxidase-catalyzed cleavage of the C-F bond has been measured potentiometrically. A linear relationship was obtained between the output voltage change and the logarithm of the analyte concentrations from 0,1 to 1 mmol/l.
