摘要：

DNA is one candidate of promising molecules for molecular electronic devices, since it has the double helix structure with pi-electron bases for electron transport, the address at 0.4 run intervals, and the self-assembly. Electrical conductivity and nanostructure of DNA and modified DNA molecules are investigated in order to research the application of DNA in nanoelectronic devices. It has been revealed that DNA is a wide-gap semiconductor in the absence of doping. The conductivity of DNA has been controlled by chemical doping, electric field doping, and photo-doping. It has found that Poly(dG).Poly(dC) has the best conductivity and can function as a conducting nanowire. The pattern of DNA network is controlled by changing the concentration of the DNA solution.
