Chem Commun (Camb). 2010 Sep 28;46(36):6699-701. doi: 10.1039/c0cc01958e. Epub 2010 Aug 16.

Abstract

Confocal fluorescence demonstrates that single molecules of dye-labelled Cytochrome C or B5 containing paramagnetic Fe(III) can be magnetically placed into the interstices of super-crystal which is composed of three dimensional regular arrays of Fe(3)O(4) nanoparticles.
