Abstract: Small atomic gold clusters in solution, Aun, stabilized by cetyl trimethylammonium bromide (CTAB)and cysteine, have been synthesized potentiodynamically in quiescent aqueous solutions. The electrodissolution of gold to gold ions during an anodic scan and subsequent cluster formation during a cathodic scan in underpotential (UPDD) and overpotential dissolution–deposition (OPDD) regions were studied. The experimental potentiodynamic I–E profiles and chronoamperometric i–t transients are fit into reported theoretical models of adsorption and electro crystallization. The plausible application of clusters/cluster film to cysteine sensing based on fluorescence quenching and square wave stripping voltammetry is demonstrated
