Third-generation glucose biosensor incorporated in a conducting printing ink
article
A biosensor based on a conducting screen-printing ink for the direct amperometric measurement of glucose is described. Carbon electrode prints, containing the work, reference and auxiliary electrodes, are used as the substrate for the sensor. The active parts of the carbon ink are the redox enzyme glucose oxidase and the conducting polymer poly(pyrrole), which can communicate directly with each other. As a result, the biosensor is largely independent of the oxygen concentration. The feasibility of the described biosensor ink for screen printing is shown. © 1994.
