The condensation of 1,1'-ferrocenedimethanol and lipoic acid yields a ferrocene derivative (FcD): 1,1'-ferrocenyl bis(methylene lipoic acid ester), a bipodant linker which was used to aggregate gold nanoparticles (AuNPs). The FcD/AuNP aggregations displayed a very well-resolved signal related to the ferrocene oxidation to ferrocenium. The aggregates were found to form an efficient transducing system for a novel concept of immunosensing based on the shifting of the ferrocene oxidation potential.

The title compound, C(6)H(12)N(2)S(4), was obtained as a by-product (8%) during the reaction of the electrogenerated cyano-methyl anion with phenyl-amine, carbon disulfide and methyl iodide. The mol-ecule, with the exception of 8 H atoms, lies on a crystallographic mirror plane and is arranged around an inversion centre located at the mid-point of the N-N bond.
