Abstract
The present invention makes it possible to efficiently recognize carbon nanotubes, carbon nanohorns or modifiers thereof and to support functional compounds by fusing the ability of ferritin molecules capable of forming nanoparticles of inorganic metal atoms or inorganic metal compounds. In addition, because ferritin molecules are capable of forming two-dimensional crystals at the interface, the present invention makes it possible to align carbon nanotubes, carbon nanohorns with the use of the molecular arrangement ability of ferritin fused with nanographite structure recognition peptides. A nanographite structure/metal nanoparticle composite is constructed, wherein a nanoparticle of an inorganic metal atom or an inorganic metal compound is retained in an interior space of a protein in which a nanographite structure recognition peptide is fused or chemically bound to a surface of a cage protein such as ferritin, and wherein a plurality of nanoparticles of an inorganic metal atom or an inorganic metal compound are supported on a nanographite structure with the use of affinity of the nanographite structure recognition peptide to the nanographite structure.
