DNA is a multipurpose biopolymer that has drawn a lot of attentions in the field of nano-machines or/and nano-electronics. DNA exhibits high stability, adjustable conductance, self-organizing capability, programmability and massive information storage. It is an ideal material in the applications of nanodevices and nano-electronics. By doping with nickel ions tunes the DNA into conducting polymers. Further studies showed that nickel ions containing DNA (Ni-DNA) nanowires exhibit characteristics of memory resistor and capacitor behaviors and making them a potential mass information storage system. In summary, Ni-DNA have promising applications in a variety of fields, including nano-electronics, biosensors and memcomputing.
