Abstract:
1. An electrochemical sensor, comprising: a substrate comprising a working electrode and a counter electrode; a co-factor associated dehydrogenase disposed on the working electrode, wherein the dehydrogenase reacts with an analyte of interest resulting in generation of free electrons; and a redox mediator disposed proximate to the working electrode that assists in the transfer of the free electrons to the working electrode, wherein the redox mediator comprises a transition metal complex having the following formula: wherein wherein: R R c is an integer selected from −1 to −5 or +1 to +5 indicating a positive or negative charge; X represents at least one counter ion; d is an integer from 1 to 5 representing the number of counter ions; and L wherein at least one of R wherein L
