“…Based on observations from transmission electron microscopy, scanning electron microscopy and X-ray photoelectron spectroscopy, silver ions were shown to be deposited on the backbone of the DNA duplex, leading to morphological changes and structural rigidity of DNA molecules. With silver ions, the length and height of the DNA were approximately one third shorter and larger than that of those of native DNA [39].…”

“…Hence, making DNA conductive is essential for the application of DNA in nanoelectronics. Interestingly, low-conductance linear DNA can be transformed into a highly conductive nanowire by doping metal ions or metallisation [38][39][40]. Metal ions were shown to bind strongly to the base pairs of DNA and are enclosed by the phosphate sugar backbones.…”

DNA (deoxyribonucleic acid) is a highly versatile biopolymer that has been a recent focus in the field of nanomachines and nanoelectronics. DNA exhibits many properties, such as high stability, adjustable conductance, vast information storage, self-organising capability and programmability, making it an ideal material in the applications of nanodevices, nanoelectronics and molecular computing. Even though native DNA has low conductance, it can easily be converted into a potential conductor by doping metal ions into the base pairs. Nickel ions have been employed to tune DNA into conducting polymers. Doping of nickel ions within DNA (Ni-DNA) increases the conductivity of DNA by at least 20 folds compared with that of native DNA. Further studies showed that Ni-DNA nanowires exhibit characteristics of memristors, making them a potential mass information storage system. In summary, DNA molecules have promising applications in a variety of fields, including nanodevices, nanomachines, nanoelectronics, organic solar cells, organic light emitting diodes and biosensors.

“…Graphene can also be used as a storage medium for DNA, for hybridization, for address assembly and for the interaction of complementary chains [12]. It is also of interest to cover graphene surface by metallized DNA, which is essentially a molecular wire [1,13]. When applied, the conductivity of both graphene and the DNA molecules may change.…”

The article demonstrates a technique for fabricating a structure with the inclusion of suspended DNA threads and manipulating them using composite nanotweezers with shape memory effect. This technique could be suitable for stretching of nanothin DNA-like conductive threads and for measuring their electrical conductivity, including the I-V characteristic directly in the electron microscope chamber, where the nanotweezers provide a two-sided clamping of the DNA tip, giving a stable nanocontact to the DNA bundle. Such contact, as a part of 1D nanostructure, is more reliable during manipulations with nanothreads than traditional measurements when a nanothread is touched by a thin needle, for example, in a scanning tunnel microscope.

Direct conductivity measurements of thin uniform gold-coated DNA nanowires are presented. Gold-coated DNA conductive wires deposited on a mica surface are visualized by SEM and conductivity of the wires are measured using nanomanipulators built inside the microscope. The measurements show that the conductivity is limited by defects, and the thicker the coating the higher the conductivity of the wires. These gold-coated DNA nanowires are promising candidates for molecular electronics. DNA-base nanomaterial to be used in new DNA-based molecular electronics.
