Abstract

original image

Brücken schlagen: Die elektrische Leitfähigkeit einzelner die Lücke zwischen zwei Kohlenstoffnanoröhren überbrückender Metallo-DNA-Duplexe kann gemessen und durch den Einbau von Cu2+-Ionen (gelbe Kugel im Bild) geschaltet werden. Diese Ergebnisse bilden die Grundlage für Studien an der Schnittstelle zwischen molekularen Nanobauteilen und biologischen Systemen.
