The single-molecule conductance of DNA was found to increase by over four fold upon intercalation, while the conductance nearly unaltered upon groove-binding. These effects are interpreted on the basis of the electronic interaction of the DNA-binding molecules with the stacked DNA bases.
发现DNA的单分子电导在嵌入时增加了四倍多,而在沟槽结合时电导几乎不变。这些效应是基于DNA结合分子与堆叠的DNA碱基之间的电子相互作用来解释的。
