Porous Protein Crystals as Reaction Vessels for Controlling Magnetic Properties of Nanoparticles

Authors


Abstract

original image

Magnetic bimetallic CoPt nanoparticles are synthesized in the solvent channels of hen egg white lysozyme crystals by the reduction of Co2+ and Pt2+ ions pre-organized on the interior surface of the solvent channels. By using different lysozyme crystal systems, the magnetic properties of CoPt nanoparticles can be controlled.
