Abstract

original image

DNA-based hybrid materials when integrated into nanodevices can serve as conductive biocompatible bridges that may interface electronic circuits with biological systems. As X. Guo, M. Shionoya, and co-workers report in their Communication on page 8886 ff, the electrical conductance of individual metallo-DNA duplexes bridging a carbon nanotube gap can be measured and switched by use of Cu2+ ions.
