Direct Conductance Measurement of Individual Metallo‐DNA Duplexes within Single‐Molecule Break Junctions

Abstract

Bridging the gap: The electrical conductance of individual metallo-DNA duplexes that bridge a carbon nanotube gap can be measured and switched by use of Cu2+ ions (see picture, yellow sphere: Cu2+). These studies form the basis for new exciting research that interfaces molecular nanodevices with biological systems.
