The three types of glucose electrode discussed here illustrate the major facets of design and operation of enzymatic amperometric sensors. Examples of amperometric enzyme electrodes for other substrates are shown in Table 7.3. The actual design details of these sensors depend on the enzyme kinetics involved and on the operating conditions under which they are used.

A significant proportion of the published work has been concerned with the study of glucose oxidase (GOx EC 1.1.3.4) immobilized in poly(pyrrole). This is in part due to interest in amperometric enzyme electrodes for glucose measurement and in part to the fact that GOx is a very robust enzyme and poly(pyrrole) is very easy to polymerize from aqueous solutions thus conditions required to immobilize the enzyme are not demanding. In addition to the GOx/poly(pyrrole) system, a range of other enzymes and other electropolymerized films have been investigated.
