Abstract:
Ferritin nanoparticles have been deposited immobilized onto a properly modified gold surface by specific covalent bonding through lysine rests at the ferritin external surface. Atomic force microscopy (AFM) images confirmed the existence of a single ferritin monolayer. This is an easy and flexible route to form stable ferritin networks, which are covalently fixed to a gold substrate.
