AbstractA method is proposed to fabricate a devices containing lambda phage DNA, methylated lambda phage DNA, and calf thymus DNA molecules. The study observed that the double stranded DNA molecules have ambipolar charge transport properties with current characteristics. The study used drop casting, molecular stretching, and trapping methods to cast DNA molecules on the top of Au patterned devices. The scanning electron microscopy (SEM) was used to verify the coverage of the devices the the DNA molecules. It was observed during the study that the negatively charged DNA molecules can form a film with increasing thickness. The study found that the drop cast devices prepared with Me-λ-DNA, λ-DNA or CT-DNA molecules showed low drain currents and reduce the interactions between the DNA molecules.
