Abstract

Thumbnail image of graphical abstract

Filmvorstellung: Dünne Filme, die durch exponentielles Schichtenwachstum erzeugt wurden, zeigen hohe Diffusivitäten und lassen sich leicht mit anorganischen Nanopartikeln infiltrieren. Die Filme können molekulare Systeme abhängig von der Schichtzusammensetzung aus Lösungen sequestrieren und liefern oberflächenverstärkte Raman-Signale (SERS) mit hoher Intensität (siehe Bild).
