What is Immobilized nitro-fluorenone derivatives as electrocatalysts for NADH oxidation about?
A new family of redox mediators, nitro-fluorenone derivatives, is used to modify the surface of glassy carbon electrodes. The stable, adherent thin layer can be transformed electrochemically into the corresponding hydroxylamine compound. The completely reversible two-electron oxidation of the hydroxylamine group leads to the nitroso compound, which exhibits high catalytic activity in the electrooxidation of reduced nicotinamide coenzyme (NADH). A gradual shift of the redox potential towards more positive values was observed when increasing the number of NO 2 substituents in the catalyst molecule. Oxidation of NADH at potentials as low as -50 mV versus Ag AgCl was obtained, and catalytic currents are proportional to the concentration of NADH over the range 5 mM-2 mM. The rate constant for the catalytic process has been evaluated by cyclic voltammetry and rotating disc electrode measurements and typical values of the order of 10 4 M -1 s -1 are obtained.
