Abstract
► Monodisperse 5-10 nm size nanoparticles were prepared using sodium citrate as the reducing/stabilizing agent. ► Reversing the order of addition used in the Turkevich method results in monodisperse nanoparticles. ► Chloroauric acid reactivity plays a key role by controlling the rate of oxidation of citrate into acetone dicarboxylic acid. ► The system exhibits a 'memory' of the order of addition, even for conditions resulting in slow reduction.
