The Electrochemical Behavior of Nanoscale Cobalt and Iron Mineral Cores in Ferritin Protein Shells

摘要

This paper examines the redox potentials and electron transfer behavior of mineral cores that have been inserted into the hollow interior of ferritin protein molecules.A ferritin containing a mineral core represents a potential building block for nanometer power systems.The feasibility of using such a building block requires an understanding of the electrochemical behavior of the core material and the influence of the protein on that behavior.The present study examines the behavior of cobalt and iron cores which had been inserted into horse spleen ferritin (Fe(III)HoSF).
