Protein immobilisation on perpendicularly aligned gold tipped nanorod assemblies

Chem Commun (Camb). 2011 Mar 7;47(9):2655-7. doi: 10.1039/c0cc05182a. Epub 2011 Jan 11.

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.
