Abstract
Section titled “Abstract”A novel co-reactant-free electrogenerated chemiluminescence (ECL) system is developed where Ru(bpy)<sub>3</sub><sup>2+</sup> emission is obtained on boron-doped diamond (BDD) electrodes. The method exploits the unique ability of BDD to operate at very high oxidation potential in aqueous solutions and to promote the conversion of inert SO<sub>4</sub><sup>2-</sup> into the reactive co-reactant S<sub>2</sub>O<sub>8</sub><sup>2-</sup>. This novel procedure is rather straightforward, not requiring any particular electrode geometry, and since the co-reactant is only generated in situ, the interference with biological samples is minimized. The underlying mechanism is similar to that of the Ru(bpy)<sub>3</sub><sup>2+</sup>/S<sub>2</sub>O<sub>8</sub><sup>2-</sup> system; however, the intensity of the emitted signal increases linearly with [SO<sub>4</sub><sup>2-</sup>] up to ∼0.6 M, with possible implications for analytical uses of the proposed procedure.
