Endowing a Ferritin‐Like Cage Protein with High Affinity and Selectivity for Certain Inorganic Materials

Abstract

Caged nanoparticles: Apoferritin and Fe-filled ferritin were constructed from the modified gene for the L chain of horse ferritin so that target-specific peptide aptamer sequences against carbon nanohorns or Ti were appended at their N-terminal ends. The TEM image shows a specimen from single-wall carbon nanohorns incubated with Fe-filled ferritin-like protein. These cage proteins could be used to assemble a wide variety of inorganic nanocomposite materials.
