Abstract

original image

Dünne Filme von DNA-Nanopartikel-Übergittern ließen sich mithilfe eines schrittweisen Assemblierungsprozesses Schicht für Schicht auf DNA-Substraten abscheiden. Ein neues Designprinzip für programmierbare Kristalle wird daraus abgeleitet: Das Übergitter nimmt eine Orientierung an, in der die komplementären DNA-Wechselwirkungen mit einer gegebenen Kristallebene maximiert sind.
