Abstract

Von oben und von unten: Schneisen in selbstorganisierten Monoschichten (SAM) auf einem Goldsubstrat wurden mit Peptidlinien gefüllt. Eine Kombination von Top-down- (Peptidnanolithographie) und Bottom-up-Verfahren (Biomineralisation) ermöglichte es, monodisperse Goldnanopartikel auf diesen Peptidlinien abzuscheiden (siehe Bild). Die Zahl an Nanopartikeln auf den Linien war durch die Breite des Peptidmusters bestimmt.
