摘要

利用导电原子力显微镜（conductive atomic force microscope

c-AFM）的扭转共振隧穿电流模式

在绝缘衬底云母上对还原石墨烯（rGO）和DNA构成的复合体导电性做了初步的测量。测量结果表明

石墨烯能很好地吸附双链DNA分子形成连接复合体

c-AFM实验证明复合体中的双链DNA分子不具有长程电子输运能力。石墨烯-DNA复合体电导能力的测量对利用石墨烯及DNA分子进行分子器件构建研究具有参考价值

同时实验测量方法具有一定的实用意义。

Abstract

In this paper

conductive atomic force microscope(c-AFM) is employed to investigate the conductance of composite structure of reduced graphene oxide(rGO) and double strand DNA molecule on isolated mica substrate

in torsional resonance tunneling current mode.The results indicate that graphene trends to absorb double strand DNA molecules to form composite body

and the c-AFM detections indicate that such a composite body is ineffective in long distance electron transfer

due to the high electric resistance of DNA.This work is of significance for explorations of applying graphene and DNA into molecular devices

and our measurement method is of practical value.
