Abstract
In this paper, the directed alignment methode of the DNA molecule between the Au electrodes was suggested for the application of nano devices. To fabricate the nano device coated DNA, 2-Aminoethanthiol(AET) was coated on Au electrodes which was formed using photo-lithography process on $SiO_2/Si$ substrates. In general, the AET that was a positive charge with $NH^{3+}$ was strongly combined under the electrostatic interaction with DNA molecule which had to be a negative charge. The DNA molecules could be easily aligned between Au electrodes coated with AET. The structures of the DNA molecules were investigated using AFM(Atomic force microscope), they were changed from single types to bundle according to the AET concentrations.
