Programmable Redox State of the Nickel Ion Chain in DNA

DNA is a nanowire in nature which chelates Ni ions and forms a conducting chain in its base-pairs (Ni-DNA). Each Ni ion in Ni-DNA exhibits low (Ni2+) or high (Ni3+) oxidation state and can be switched sequentially by applying bias voltage with different polarities and writing times. The ratio of low...
