Abstract

A multi component assembly consisting of the redox protein cytochrome c (cyt c) immobilised onto vertically aligned gold tipped semiconductor nanorods is described. Cyt c was successfully immobilised using a thiol linker. A faradaic response demonstrated that the protein is electroactive in this ultra high density array.
