DNA is a native template to chelate and align Ni ions in base-pairs of DNA and created a DNA guided Ni ion chain (Ni-DNA). By conjugating the Ni-DNA with two terminal molecular device a programmable multi-state memristive system with an added capacitive component has been developed. The multi-state information can be written, read, and erased on this DNA memristive system. Thus, this Ni-DNA conducting nanowire can be used in combination with other two-terminal devices for a variety of applications in memory as well as n-nary computing. This study also indicates the biomolecules-based self-organized nanostructure can be used as a template for nanodevices fabrication.
