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

摘要

DNA, as the product of million years of evolution, possesses the maximal density of functionalities embedded in its framework and superior sequence-specific self-assembly properties that make it a useful scaffold for the organization of molecules into higher-order nanostructures for the development of functional nanoscale devices and materials. In this context, one major effort is to transform DNA into a conductive material that would make a significant contribution to the development of the vibrant field of DNA-based molecular electronics.
