Abstract

Biosensor for amperometric measurements wherein the measuring electrode (34) is made of an electrically conductive carrier made of carbon which is saturated with a platinum metal in colloidal form wherein a lead-off contact (10) of vitreous carbon runs from the measuring electrode (34). The porous carrier (6) is saturated with an enzyme suitably glucose oxidase for the determination of glucose wherein the surface of the carrier (68) is protected against the environment by a membrane (70).
