Präzisionsarbeit: Ein einfaches, einstufiges Polyolverfahren ermöglicht die Synthese von monodispersen, einkristallinen Au-Cu-Dimetallnanowürfeln. Durch Feinjustierung der Reaktionsparameter lassen sich die Dimensionen der Nanowürfel (zwei Beispiele mit 23 und 5 nm sind gezeigt) ebenso einstellen wie ihre Gold- und Kupferstöchiometrie.
