title: Porous protein crystals as reaction vessels for controlling magnetic properties of nanoparticles.
abstract: Magnetic bimetallic CoPt nanoparticles are synthesized in the solvent channels of hen egg white lysozyme crystals by the reduction of Co(2+)  and Pt(2+)  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.
