It is intended to provide a peptide or a phage recognizing nanographite
structures and thus enabling efficient recognition, binding, separation
and alignment of nanographite structures such as carbon nanohorns or
carbon nanotubes, an artificial protein or a chimeric molecule comprising
the above-described peptide bonded to a functional peptide, a protein, a
labeling, etc., and a complex of the above-described peptide molecule,
artificial protein or chimeric molecule with a nanographite structure. By
panning peptide-presenting phages bonded to nanographite structures, a
nanographite structure-binding peptide capable of specifically
recognizing nanographite structures such as carbon nanohorns or carbon
nanotubes is obtained.
