Nanoscale solid-state electron transport via ferritin: Implications in molecular bioelectronics

In this article, an outline of the different parameters (for example, temperature, metal core reconstitution, compressive pressure) that control solid-state electron transport through the iron-storage protein ferritin, in monolayer and multilayer form, is presented. It is shown, primarily by using the local probe measurement methods like scanning tunnelling​ microscopy/spectroscopy and current sensing atomic force microscopy/spectroscopy that ferritin is a potentially versatile bioelectronic material since its electron transport properties can be controlled by various simple means and its film structure can be largely tailored as per need.
