Abstract

A controllable and reproducible bipolar memristive protein nanodevice is fabricated by chemical immobilization of ferritin molecules within on-wire lithography-generated nanogaps. Control experiments suggest that programmable resistive switching is due to the electrochemical processes in the active centre of ferritin. Such ferritin-based nanodevices with reversible resistance can be used for nonvolatile memory based on write-read-erase cycles.
