Two distinct proteins, streptavidin and HupR, bind and form regular helical arrays on the surface of multiwalled carbon nanotubes under appropriate conditions (see picture). The decoration of the outer surface of these nanostructures with biological macromolecules was investigated by electron microscopy.
