Porous protein crystals as reaction vessels for controlling magnetic properties of nanoparticles

Small. 2012 May 7;8(9):1314-9. doi: 10.1002/smll.201101866. Epub 2012 Mar 2.


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.
