A novel bifunctional protein supramolecule for construction of carbon nanotube–titanium hybrid material

Carbon nanotube–TiO2 hybrid materials with many nano-scale cavities were realized using a bifunctional protein supramolecule possessing carbonaceous material-binding peptides and Ti-binding peptides. The obtained structure was confirmed to consist of a central nanotube, surrounding proteins, and a swathing titanium-layer. All processes were carried out at room temperature, using an environmentally friendly method.
