Abstract
The present invention provides for electrode assemblies and methods in which electron transfer between a redox reaction product and an electrically conductive electrode material is facilitated by a metallo macrocyclic compound, preferably a metallo isoindole ringed compound and more preferably a ferro isoindole ringed compound. The redox reaction is usually catalysized by a redox enzyme, such as an oxidase.

32. A method for electrically detecting the presence of an analyte comprising:
-
measuring an electrical current from a redox electrode comprising an electrode material and a ferro isoindole ringed compound in fluid communication with an oxidase, wherein said oxidase catalyses a redox reaction that corresponds to the presence of an analyte and produces a product that either
1) directly chemically oxidizes or reduces said ferro isoindole ringed compound or
2) indirectly oxidizes or reduces said ferro isoindole ringed compound, andwherein said oxidase is attached to a first analyte binding moiety. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40)
