摘要

PCT No. PCT/CH92/00034 Sec. 371 Date Oct. 19, 1992 Sec. 102(e) Date Oct. 19, 1992 PCT Filed Feb. 19, 1992 PCT Pub. No. WO92/14836 PCT Pub. Date Sep. 3, 1992.A sensor for measuring the amount of a component in solution is disclosed. The sensor has a measuring electrode with at least one current collector, electrically connected to one of the electrical contacts and coated with a mixture comprising at least one oxidation-reduction enzyme specific to said component and at least one mediator transferring the electrons between said enzyme and said current collector wherein the mediator is a transition metal complex with at least one bipyridine, terpyridine or phenanthroline ligand substituted by at least one electron donor group. This sensor is particularly useful in the detection of glucose.
