Abstract

original image

Ein Blick in das Innere: 3D-Flugzeit-Sekundärionenmassenspektrometrie (TOF-SIMS) im Doppelstrahlmodus ermöglicht die Detektion der charakteristischen Biopolymere an der Oberfläche von Pflanzenzellwänden und in darunterliegenden Schichten. Die laterale und vertikale Verteilung der Hauptbestandteile kann kartiert werden, und die Architektur der Pflanzenzellwand lässt sich so auf der Submikrometerskala visualisieren (siehe Bild: grün Cellulose, rot Lignin).
