Jülicher Forscher schauen ins Innere von Molekülen

(PresseBox) (Jülich, )
Zum Alltag von Nanotechnologen gehört es, mit ihren Mikroskopen einzelne Atome zu untersuchen. Schwierig zu beobachten waren bislang jedoch Atomstrukturen, die sich im Inneren von organischen Molekülen befanden. Im renommierten Fachmagazin Physical Review Letters (DOI: 10.1103/PhysRevLett.105.086103 ) erklären Jülicher Forscher nun ihre neuartige Methode, die den "Röntgenblick" ins Molekül ermöglicht. Sie könnte es einfacher machen, organische Halbleiter und Proteine zu analysieren.

Für den Blick in die Nanowelt nutzten die Jülicher Forscher ein Rastertunnelmikroskop. Dessen dünne Metallspitze fährt wie die Nadel eines Plattenspielers über die Probenfläche und registriert mittels kleinster elektrischer Ströme die atomaren Unebenheiten und Unterschiede von rund einem Nanometer (yeehc Njmifocbmdgi Miazmqdsmp).
